Better papercollision

Diagonal bounding boxes are no longer root 2 larger than they should be. Testwad is <root>/toaster/sawb.wad. Nice and simple.

Slopewall transfer

As @Nev3r wants. Go along a slope, hit a wall? LAUNCH! Well, I mean. He wants it slightly less weak. I have already made it less weak than P_SlopeLaunch.

Also also I made the trail that goes behind the player when they're rolling take into account vertical momentum as well as horizontal, so that being launched directly up didn't leave you trailless.

Test with <root>/!LatestSRB2Files/srb2win_branch_transfer.exe and <root>/Nev3r/ACZMaster.wad (roll down slope directly in front of you).

Hardcode some stuff in patch.dta

Does what it says on the tin. I wanted to do the Christmas objects before creating the merge request, but it's advisable to block patch.dta's updating as little as possible, and I'm slowing down on my own development speed, so better move quickly.

Also, I hardcoded a nicer rolling trail aura from smiles.wad/smilespatch.wad, a nicer fire from new CEZ1, made the Koopa shell more fun and made the spinning flame jet WAY less hacky.

Check <root>/!LatestSRB2Files/ for srb2win_branch_hardcode.exe and the patch.dta fork it runs off, which includes all the necessary changes here.

Added modified Mario shells. They now hurt everyone if you touch them from the side, and can be stopped by anyone if they stomp on their tops.

Revamps of several dated linedef type effects

Felt like being productive so made some things I hate suck less.

Linedef type 7 (flat alignment) now works as follows.
* Linedef angle (from v1 to v2) is flat angle.
* Origin of flat is manipulated to match v1's coordinates - unless ML_NOKNUX is flagged, in which case uses frontside x and y offsets as flat offsets instead.
* ML_NOSONIC prevents changing floor.
* ML_NOTAILS prevents changing ceiling.
* Both of the above flags at once prints a warning.
* (THZ and probably a few other maps need updating.)

Linedef type 540 (friction) now works as follows.
* Controlled by x offset instead of length - offset of -100 is maximum iciness, offset of +483(!!!) is the maximum sludginess BUT things are scaled such that +100 is about the maximum sludginess any reasonable human being would want in a level, 0 is ORIG_FRICTION)
* Not reliant on a sector special to function (can be applied solely by tag to in-map sectors or solid FOF control sectors)
* Uses less memory, perform less calculations, and not bug out objects which just happen to use movefactor for something
* PHYSICS CHANGE: Low friction surfaces actively impede your acceleration (and make your animation speeds faster to give off that Looney Tunes out-of-control effect)
* (ACZ and Frozen Hillside needs updating.)

Sector types 1 and 3 in section 3 no longer do anything.

Linedef type 3 (zoom tube) now works as follows.
* Abs of frontside x offset is speed in units of FRACUNIT/8.
* Abs of frontside y offset is waypoint sequence number.
* Effect 4 flag rotates the player to match the waypoint direction (same as before).
* (ERZ needs updating.)

Linedef type 11 (rope hang) now works as follows.
* Abs of frontside x offset is speed in units of FRACUNIT/8.
* Abs of frontside y offset is waypoint sequence number.
* Effect 1 flag makes rope transfer one-way. (same as before)
* No climb flag makes rope static. (same as before)
* (ACZ and maybe ERZ need updating.)

Linedef type 258 (laser) is almost the same as before, but has altered functionality.
* Its flashing is less obnoxious. (56.25% to 68.75% instead of 100% to 0%, at half the speed)

Linedef type 14 (Bustable block parameters) is new, and works as follows.
* Tagged to the control sector of a block that is likely to be busted (via executor or collision, doesn't matter)
* Concatenation of frontside textures is MT_ object type to spawn, defaults to MT_ROCKCRUMBLE1 if not present
* Sound played when being busted is object type's activesound
* Frontside x offset is spacing (in fracunits) of spawned particles, defaults to 32<<FRACBITS
* Frontside y offset is the fuse of spawned particles in tics, defaults to 3*TICRATE, if set to -1 fuse is not set
* Effect 1 flag makes particles "fly out" horizontally and vertically from the center of the FOF

Sector types 7 through 15 in section 3 no longer do anything.

Linedef type 250 (Mario Block) is almost the same as before, but has new functionality and is slightly different in another way.
* No Climb flag turns it into a brick block (set on Custom FOF via presence of FF_SHATTERBOTTOM - busts when hit from the bottom, player hits their head/fist/whatever, no more upwards momentum)
* Effect 1 flag makes it an invisible block (set on Custom FOF via absence of (FF_SOLID|FF_RENDERALL|FF_CUTLEVEL) - intangible from every side except the bottom. Becomes visible and tangible when it's hit once)
* Only updates side textures when moving down or stationary, not whilst moving up - more fidelity to the source material, less processing on the CPU, everyone wins.
* If FOF master linedef has a backside, then: [If there's items in it the FOF's flats are set to that of the backside sector's ceiling, otherwise the floor.] Otherwise, no flat change.

Linedef type 4 (Speed Pad parameters) now works as follows.
* Frontside x offset is speed in fracunits.
* Effect 4 flag doesn't center the player. (same as before)
* Effect 5 flag sends them off in rolling frames.
* Frontside upper texture is sound to play on launch, defaults to sfx_spdpad when not given

Sector type 6 in section 3 no longer does anything.

Object type 757 is changed as follows, and no longer works on its own - see Linedef type 15 for more details.
* Tag via its angle field
* Number of objects to spawn per tic around it via its z field, if zero then just spawn at center
* Is flipped if given MTF_OBJECTFLIP.
* (ERZ and Seraphic Skylands - if we use that map - needs updating)

Linedef type 15 (Fan particle spawner parameters) is new, and works as follows.
* Tag is tag of object(s!)
* Object type set via concatenation of frontside textures, MT_PARTICLE is default
* The length of the linedef is the radius the particle is spawned out (zeroed if z field is 0)
* Frontside x offset is speed upwards
* Frontside y offset is number of degrees to turn each tic (zeroed if z field is 0)
* Frontside floor and ceiling heights are the heights in which the particle is bound through some fun mathematics

A_ParticleSpawn is changed, too.
* Object type is now changed through actor->threshold instead of var1 to support Linedef type 15.

Test executable uploaded at /toaster/srb2win_branch_flatalignment.exe on the ftp.

Test file uploaded at /toaster/flatalignment.wad on the ftp.

Breaks compatibility with 2.1 so put in internal.

Plane displacement

Basic support for plane displacement, no netplay support as of writing but this is what Nev3r wanted moreorless at least.

Linedef types 66-68 are the plane displacement specials; 66 = move floor only, 67 = move ceiling only, 68 = both

Front sector = control sector
Tag = tag of target sectors to be moved whenever the control sector floor moves
Linedef length = movement factor relative to control sector movement, 256 = 1:1 with control sector. 128 is half as much, 512 is twice as much, etc.

Whenever the control sector floor moves (not ceiling, never ceiling), the selected planes of the tagged sectors all move (mind, they have a tic delay due to how it all works, it's not perfect really). No support for reverse speeds yet sorry.

EDIT: oh, btw, test exe and test map are included in my folder on the FTP (srb2win-plane-displacement.exe and plane-disp-test.wad, respectively)

* Made the name of P_PrepareSlopeToWallTransfer (now P_GetWallTransferMomz) make sense.
* Bugfixed the case where you couldn't reliably guess the angle of the wall you just hit.

* Seriously reworked a lot of stuff behind the scenes, thanks to Red's comments.
* More consistent behaviour.
* Launching power is now scaled to the slope's angle relative to the wall you hit, so no massive launches when you hit the side of a steep slope.
* The code is a lot messier and the function name doesn't make any sense any more, so I need to clean that up in the morning.
* Need to figure out how to prevent tiny launches that uncurl you when spindashing up against walls.
* Spindashing trails now takes into account vertical momentum as well as horizontal - it was stupid not seeing your spintrail just because you weren't moving very fast horizontally!

No exe uploaded because it's almost 2am.

Please note Brak flames use a FF_ANIMATE state instead of the normal flame ones because they are spammed a lot, and the normal ones make particles.

GFZ3 Unfuckening

Some tweaks to the GFZ3 Eggmobile's behaviour to make it less frustrating for old and new players alike.

* GFZ3 Eggmobile's laser won't change its angle when you move left and right anymore.
    * Changed because its ability to move quickly was extremely punishing for new players (see ProJared's youtube video on the matter).
    * http://gfycat.com/PassionateUnknownAgama (the twitching on the third laser has been fixed since this was recorded)
* GFZ3 Eggmobile will, when too far away from the ground and moving upwards, slow itself down vertically.
    * This was punishing and annoying for both old and new players alike.
    * http://gfycat.com/CornyLeftDungbeetle (old values - the typical settling height is slightly lower now)

Fixed flame jets. (I'll upload the patch.dta required to run this exe when I'm ready to make a merge request.)

* ALMOST SORTA IMPLEMENTED A NON-HACKY SPINNING FLAMEJET. For some reason, they wanna step down onto the platform - and I've been figuring this out for too long to see what's causing that tonight.
* Hardcoded a bunch of stuff from patch.dta. All works fine, but still more to do.

No more double-decker Detons

Oversight of a tiny hack when working on the flickies branch meant detons released twin flickies when hitting stuff. As cute as that is, it's also pretty weird.

A spike bug no more

Jumping at spikes on FOFs in reverse gravity - most notably in ERZ3 - no longer teleports you downwards into the death pit beneath it.

See merge request !157

Fixed a stupid bug involving jumping at spikes on FOFs in reverse gravity caused by my own incompetence/assumptions.

Fixed crash bug. It's weird that linedefs' backsides aren't NULL but are instead 0xFFFF when invalid, so instead I used something which DOES take null pointers as a parameter.

Merge branch 'master' of http://git.magicalgirl.moe/STJr/SRB2Internal.git into flat_alignment_revamp

(I COULD have hacked around the hack, but when a line tells you it's a hack and it makes things work by removing it, you remove it.)

This reverts commit 6476cf3c, reversing
