- Buffed crouch landing; lasts slightly shorter and cuts speed less
- Support for swimming! Knuckles has slightly different glide controls when he has swim sprites underwater
- Improved glide controls in 2D mode
- Super Knuckles perks: land from a glide or latch onto a wall to generate a shockwave and damage nearby enemies
- Refactored skid dust
- Made super sparks use FF_FULLBRIGHT
- Added P_SpawnSkidDust and P_Earthquake to Lua

This is accomplished by simply preserving
the player's body after disconnecting.

Bodies will despawn after the number of minutes
specified by the "rejointimeout" console variable (float).
A value of 0 disables the feature completely.

Clients rejoining are identified by their IP address,
and may rejoin even if the server is full or joins are disabled,
for as long as their body remains.

From a technical standpoint, when the user disconnects,
the player they were controlling does not leave,
the underlying player_t just keeps working normally,
except it does not receive any input anymore.
When the user reconnects, they are simply "relinked"
to their player_t.

Those "soulless" players can be identified through
their "quittime" field, which is the number of tics
elapsed since the user disconnected, or zero
if still connected. "quittime" is exposed to Lua.

This only takes effect in co-op,
and can be disabled with "exitmove off"

Other things I missed. Also added SF_NONIGHTSROTATION. Do I even have to keep the old behaviour? I have no idea.

    * Red and yellow Boost panels!
        * Added because SUBARASHII and KIMOKAWAIII had several levels using them, and I wanted to make them look better.
        * https://cdn.discordapp.com/attachments/359091121789468672/634486669202161674/srb20015.gif
        * Uses the mapthingnums of Glaber's SOC resource boosters, but absolutely nothing else - not even the magnitudes.
        * Apply MF_AMBUSH to force the player into a spin - even if they don't have a spin ability!
    * Banpyura!
        * A Crushstacean with a spring instead of a crushclaw.
        * https://cdn.discordapp.com/attachments/428262628893261828/634432099306176512/srb20019.gif
        * Wanted this for a while, finally added it.
* Improved springs.
    * Add pw_noautobrake to disable autobrake for half a second when touching yellow horizontal springs, and a second when touching red ones, even on the ground.
    * Add pw_justsprung to disable directionchar for a few tics while touching any springs with a horizontal component to their velocity.
    * Add the diagonal spring flag options Red and Yellow Diagonal Springs have to the Blue Diagonal Spring as well.
    * Started but decided against a tip of the hat to the CD spring spin, hidden behind #define SPRINGSPIN.
* Make directionchar "lag behind" a little bit in waterslides.
* Improved flame jets.
    * They now use new sprites for having their flames move upwards and sideways, instead of having them always face downwards like in 2.1!
* Fixed a mixed declaration and code error in A_RolloutRock. (Sorry Lach!)
* Make the Amy Cameo only spawn in SP, Record Attack, or Co-op unless it's the Clone Mode.
* Improved ZB config.
    * Add above new types.
    * Add Blue Diagonal Spring, which existed in the source but not the config.
    * Re-order enemies in ZB config by zone (but keep them in the Enemies section only).

Current known issues: players detached from the ball via any means other than jumping or pain do not have their ball reset properly

* Store gravflip (resolves #206) and destscale in starposts. (Using the same field, taking advantage of the fact that object scale will always be positive!)
* Update the function signature of P_MixUp to accomodate both it and drawangle instead of doing it outside of the function.
* If the player is spawning from the start of the stage and it's from the ceiling, be in fall frames as requested (resolves #191).

* Smoothen Pity Shield animation to go with sphere's updates to Nev3r's sprites.
* Added LHRT object, designed to be summoned with CA2_MELEE.
    * Gives a pink Pity Shield (SH_PINK) on same-team player contact.
    * Deals damage to non-player enemies.
    * Harmlessly fades into nothing when touching an enemy player, players with SH_PINK already, and players capable of applying SH_PINK to others (through non-Lua methods).
* Basically, you-know-who is the Healer of the party whenever they're around. Fun consequences for the Co-op and CTF metas.

# Conflicts:
#	src/p_setup.c

There is no lapfinishedtime because [mare]finishedtime refers to when Egg Capsule is destroyed. That concept does not apply to laps.

* player->drone mobj variable
* P_MoveNiGHTSToDrone, will change later

There is no lapfinishedtime because [mare]finishedtime refers to when Egg Capsule is destroyed. That concept does not apply to laps.

There may not be a point to this, other than to be consistent with how spheres are tracked. If non-special stage NiGHTS should tally a ring bonus, this may be useful.

OLD SPECIAL STAGES:
* Spheres in old special stages instead of rings!
* Individual timers in old special stages instead of a global one!
* Old special stages use a variant of the NiGHTS HUD now!
* Special stage damage in old special stages loses 5 seconds of time instead of 10 rings/spheres!
* All damage gained through old special stages is converted to special stage damage! As a consequence, the special spikeball has no need to be special anymore.
* Made emerald gaining function be based on special stage number rather than gained emeralds!
* Consistency with...

NiGHTS SPECIAL STAGES:
* Spheres now flash in bonus time. https://cdn.discordapp.com/attachments/400761370800422922/452590553100713984/srb20032.gif
* Sphere and ring mapthingnums are now less fucked up in 'em. (Rings are 300, same as usual, while Spheres are now 1706 replacing NiGHTS Wings.)

SPECIAL STAGES IN GENERAL:
* useNightsSS is now dead. Each individual special stage is now assessed for NiGHTS-mode behaviour based on maptol & TOL_NIGHTS.
* CRAWLA HONCHO\n CAN NOW BE\n SUPER CRAWLA HONCHO end tally modification now also includes a mini-tutorial on turning super. https://cdn.discordapp.com/attachments/400761370800422922/452844894113759233/srb20036.gif
* SONIC GOT A CHAOS EMERALD? https://cdn.discordapp.com/attachments/400761370800422922/452623869497573386/srb20034.gif

NiGHTS NON-SPECIAL STAGES:
* Colour Chips and Star Chips! Replaces Spheres and Rings of NiGHTS Special Stages.
* Colour Chips turn yellow in bonus time.
* Ideya!
* Its own "drowning" music!
* All of the object types for Dream Hill.
* GIF: https://cdn.discordapp.com/attachments/400761370800422922/452844894113759233/srb20036.gif

RANDOM BS:
* Turn super with the spin button instead of the jump button!
* Followmobj now correctly set with P_SetTarget instead of pointer assignment.
* Emerald hunt uses new sprites!
* Made unlock noise different from emblem gain noise! (It's the CRAWLA HONCHO CAN NOW TURN yadda yadda sound from S3K now.)

Smiles follow-mobj initial support! Still using a Lua hook to follow closely behind, but now it doesn't need to be a generic thinkframe. Woo!
