Let Grow/Shrink revert itself when it changes to 0, as well as add a function for removing either. Means we don't have to modify every single > 0/< 0 check, and is overall cleaner.
This broke MKSC in a minor way if you skip a specific item set and then take the big cut... I'll let it go anyway since its an improvement everywhere else.
This fixes two bugs:
- Makes it so that the countdown happens when all the winners are ACTUALLY in instead of the first loser, because exiting timer wasn't set for the last winner in the place this was down before
- Means that the countdown timer can be set on disconnect
Specifically: removed K_StripOther calls from touching fakes: No, none of these things need to be stripped! Also, poke K_StripOther just in case it eventually becomes relevant to have it.

Unsuffixed float constants
There's an unsuffixed float constant I can't fix because the define is outside of SRB2. We could have our own copy of Pi if we really wanted.
* Marble Zone!
* Torch decoration.
* Incense burner decoration.
* CD Special Stage 1!
* The UFO, now with improved death animation!
* Turns out I duplicated sounds that already existed in sounds.kart. When we touch up the files later, yalls can remove both `DSFUFOx`'s from it.
* Change spacing of bustable FOF debris with scale (plus increase its default a bit for less lag).
* Make a few instances of scalespeed take mapheader scaling into account.
If the player count dips below what was stored on the start of the last lap, then don't do time over so that someone can't just spectate at the end of a race out of rage. Y'all are assholes :V
A couple of the extraneous ones (karma interactions, bumper stealing, lap start notifications) have been removed outright. The rest that I could think of have been changed to use CON_LogMessage, so that they still go into log.txt when rereading a fun chat session but not showing themselves in gameplay. Necessary gameplay prints, such as players being defeated or coming back in Battle, have been kept until there's a suitable replacement for them in the future.
