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

(no actual SLOC changes)

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.
