* Slightly bigger visual size!
* Light-shadow!
* Makes player fullbright if you have it!
* Visuals finally removed instantly on shield drop!
* Uses dark background for item icons!
* Goes behind the player on some frames, faking layering!
* Replaces the CZ64-era hopping Mario guys.
* ~50% randomised colours!
* 1/9 are FANS!
* On mapload, some Chao select a random player in the server (even spectators) as their idol.
* The fans cheer for their idol when they cross the finish line in a winning position!
* They also sob when their idol loses.
* The remaining percentage are the canon Aqua.
* Minor on-field spikeball/fake radius alterations requested by Oni.
* Shield Drop...
* Whatever you've got orbiting or trailing you, DROP THEM WHERE THEY STAND. (Except for the ghost sink. That one's OK.)
* Pops your Thunder Shield.
* Happens upon ANY hit, except for deathpits.
* HUD Drop...
* Also does the above, except for the Thunder Shield thing.
* If there's any item left in your item box, pop it out as a little hovering, rotating Minecraft item!
* You can pick up the Minecraft item by driving over it if your item box is sufficiently empty, or the item which is contained within it is of the same type.
* Happens upon Size Down and battle elimination.
* Can also be forced on with `cv_kartdebughuddrop on`!
* Some other random stuff.
* Fix a bunch of `a->scale = b`'s into `P_SetScale(a, b)` form, for maximum validity.
* Make K_CleanHnextList and K_UpdateHnextList one function, since they only differed by one continue clause (and the type of their input parameter).
* Allow shrunken players to pick up item boxes again.
* Fix MF_NOCLIPTHING. (Gonna pass this fix to vanilla when I get the chance, too.)
* Break NiGHTS a little through my machinations.
Sink would only spawn its trail ever if you threw it on a tic that was (leveltime % 4 == 0), because it called its action every 4 tics instead of every tic
Sink shield that makes it double-press to use, gives the trailing item slowdown, and shows other people that you have it, but doesn't have any collision
* Make MT_GHOST's encoremapping depend on whether the source was encoremapped.
* Revamp how sector typegroup 2, type 15 inverts the encoremapping (so planes don't get awkwardly desynchronised).
* Flashing Eggman-hit players.
* Fix typo with Rocket Shoe item bar, and make it extensible for potential future purposes since I was fiddling with it anyways.
* More complete playerarrow visuals for various items.
* Eggman fake (and debug) item get sounds.
* Default hitbox height is 80
* Drone Thing parameter sets height to multiples of 32
* Player aligns by default to bottom+24 of hitbox (offsetted)
* `MTF_OBJECTSPECIAL` aligns player to hitbox top
* `MTF_EXTRA` aligns to hitbox center
* `MTF_OBJECTSPECIAL|MTF_EXTRA` aligns to real bottom of hitbox
* Goalpost and sparkle Z alignment is changed to reflect configurableness
* New entries: NIGHTSDRONE_MAN, NIGHTSDRONE_SPARKLING
* NIGHTSGOAL renamed to NIGHTSDRONE_GOAL
* MT_NIGHTSDRONE repurposed as an invisble, no-gravity hitbox
* HOWEVER, we should seriously address this again later, because the antialiasing DOES result in some unfortunate bullshit...
* Encoremap maces per Oni's request and Sal's suggestion
