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.

dumbass who forgot to stage most of the actual changes because she actually deleted all the changes and then remade them by accident

Requires charscleanup.kart. Ezo, if you want me to, I can fix up bonuschars for this tweaked system.

The turn action happens on (k_timeovercam > 2*TICRATE). This ensures it happens immediately, although it was probably fine as is

Explosion spinout fix

Last netgame tweaks

See merge request KartKrew/Kart!57

- Number of points needed to come back is now 2.
- Bombs no longer give extra points.

Even more consistency!

Bombs & fakes get 24, items get 36. Technically a slight nerf to bomb, but it's more consistent and it's so tiny of a change that it'll be unnoticeable I feel :V

Several races in a row with several people getting x2 Jawz in the same spot... sorry Oni, it's BAD. Kept the increase in the further behind spot, we'll see if it's any better

Not only did I not implement this for everything, but I also REALLY like seeing other player's. If it's a problem, then let's just turn down the fuse and/or tics
