Stupidbad-big commit, but PLEASE don't ask me to re-do this on another branch, I swear to god. I know it makes things more difficult on you, and I'm sorry for that, but I'm definitely feeling the goddamn crunch right now and I wanna take a step back from this spaghetti nightmare and clear my head.

* Do that thing where the character icons are ALWAYS 1x sized, through having two seperate lumps.
* Revamp the S_SKIN parameters to be `facerank` (rankings - equivalent of half-scale old face), `facewant` (WANTED - equivalent of old face), and `facemmap` (equivalent of old iconprefix).
* Do that thing Oni wanted where it shows two postions above and two positions below your current ranking (and you) to the left of the screen, instead of always the top 4, with some limits to avoid drawing outside of everything.
* Replace the last few shitty Mario numbers (for the left rankings) with cool, new Oni numbers.
* Change a bunch of offsets and things so the tab rankings and the intermission work nicer with 9+ players.
