Maybe if I go ahead and open this I'll actually finish it

This works, but probably needs some optimization before it's ready to merge.

Fixes human mobs appearing all fucked up on examine. Also fixes other things appearing fucked up on examine but humans were really the only one that was obvious.

Issues:

• getFlatIcon() is slow as shit. It would be great to not use it, but that may or may not be possible.
• Caching with "\ref[appearance]" is pretty awful, but the current caching system won't work for obvious reasons. I could use the same caching scheme as getFlatIcon(), but if I do that and don't find an alternative to getFlatIcon(), I might as well entirely remove bicon_cache and just use getFlatIcon()'s cache instead. I'm actually an idiot and that's not true.
