-Added a timeout for game state downloading to prevent definitive join freezes in some cases. The timeout has a minimum value of "jointimeout" and gets higher as the game state grows in size
-If the server tries to kick a joiner who is downloading the game state, they will get a timeout instead, because a regular kick would only happen once the game state has been downloaded
-Added a timeout for player ticcmd packets, again to prevent freezes to happen in some cases
-File/game state downloading is now faster, the speed is controlled by the "downloadspeed" cvar, in packets per tic
-The reason is now properly shown when the server refuses connection
-Changed the default values of "nettimeout" to 10 seconds (previously 15) and "maxsend" to 4 MB (previously 1)
-Added a "noticedownload" cvar that displays a message in the server console when someone is downloading a file

Remove all traces of SSN's old port of ZDoom's secplanes for slopes, since our slopes do not need them

-Fixed broken net commands, thus fixing (or at least greatly improving) chat/commands/joins/leaves and possibly other annoying bugs
-Updated packet name list so the debug file no longer shows garbage packet names
-Replaced byte values with actual net command names in the debug file. Only the first net command in a packet will be shown though
-Added a MOBJCONSISTANCY define that makes the game takes all revelant mobjs to be counted in the synch seed
-Added a PACKETDROP define that adds two console commands "drop" and "droprate" to simulate bad internet by dropping packets
-Added/changed comments here in there in the netcode
-Fixed a minor error that would ignore one of the urgent ack slots
-Added a space between the map name and "zone" for the messages shown in a joiner's console

(Fixes LSHIFT typing D repeatedly into chat)

Generic mobj hooks are now run before mobjtype-specific mobj hooks, and player/linedef executor hooks now have their own lists

Revert "(Messiness warning) attempt to start using SDL_SetRelativeMouseMode instead of the old hacks of making the mouse do movement without leaving the window and be hidden"

This reverts commit 347b5318.

(Too experimental, may end up adding new bugs; let's just keep it to clean up for now)

(Messiness warning) attempt to start using SDL_SetRelativeMouseMode instead of the old hacks of making the mouse do movement without leaving the window and be hidden

Seems to work so far though

This way it's easier by eye to see from the list which SDL scancode maps to which SRB2 key code

(Apparently SDLK_LMETA/SDLK_RMETA don't exist anymore in SDL2 anyway?)

This means the console command vid_info also works properly too now (well, it does nothing in OpenGL mind)

Turns out sdl12's version of this function only did stuff for DC/GP2X ports; support for them have been cut out for SDL2, so for now let's just not use the function at all

Started work on making HWR_DrawFill support V_NOSCALESTART properly ...so far I've got the console text select highlight in the right place outside of 320x200 (and 320x200 is still fine), but for whatever reason it's too large in width and height

Oh well, we're part of the way there, anyway

MobjThinker, MobjCollide and MobjMoveCollide hooks are now directly linked to the mobjtype they belong to, so you no longer iterate through all existing hooks.

...your guesses should not be treated as errors.
