WHY THE FUCK DID THESE BREAK IT AAAAAAAAAAAAAAAAAAA

why the fuck was this removed

Expose some more Kart functions, freeplay and rankings bumpers are now hud stuff you can toggle, + experimental playercmd hook

Remove mute boolean from playermsg hook, fix username stuff still being there, potential memory leaks, and added back the ip message.

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

Keeping the lua_gettop(gL) thing, otherwise the player/reason values will be pushed once to the stack each for every hook. Thanks MonsterIestyn!

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

(no actual SLOC changes)

Argh, I knew I was forgetting something! archFunc is the argument to be passed to the hooks, not tables!

This function is intended to leave the stack in the same state it recieved it.

Fixes I_Assert failure crash due to hooks working differently now.

That's supposed to be run once a frame, not once per hook
per mobj per frame you moron. If you just run it seven
thousand times a frame, of course your framerate will drop.

Stupid JTE.

Dummy, what do you think you're doing? If you
just push mobjs and players into Lua all willy-
nilly everywhere, you'll wind up generating
tons of metatables and stuff you arne't even
gonna use!

Oh. Thanks me, I'm really smart.

This _should_ solve some significant performance
issues Lua experiences. If not, I will be very
upset for having wasted so much time and effort.

There will be bugs, this kind of thing needs to
be thuroughly tested and this is just the first
iteration of it.
