* 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 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
* They're clearly not quick enough at the job, since it causes a bunch of silly race conditions.
* Instead, K_UpdateHnextList and K_CleanHnextList are in charge of removing them, which are called in the circumstances itemamount (and itemheld/eggmanheld) is changed.
* Also, tweak a few places so that trailers AND orbiters can use the same system.
Also, some minor thingies.
* Turn all the useless ```if (a) { A } else if (!a) { B }``` bullshit into ```if (a) { A } else { B }``` bullshit.
* Fix up some minor inaccuracies in the playerarrow stuff that doesn't result in creating more sprites.
* The tab and intermissions rankings...
* ...now have parity in behaviour!
* ...now properly handle player counts over 8, and no longer supports player counts over 16!
* The Item Arrow in Battle...
* No longer develops any extremely stupid bugs due to Orbinaut sprites that makes all objects in state S_INVISIBLE develop <!>'s! (Ask me about this if you're curious as to how it affected everything else too.)
* 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.
