[MERGED PR] Removes Dwarfism

[Varali]

While we could make dwarves work, my favorite suggestion being fitting the dwarf sprite down to match monkey clothes, I don't think dwarves are a big feature worth investing a lot of time on. It's not a particularly interesting feature and I haven't seen many players embrace it and use it much. The most I've seen it come up is people suiciding when their mutantrace is overriden by the dwarf miner random roll or seeing it in the GeneBooth. We have skeletons for weird human subraces, I'd rather we focus on sprucing up skeleton and other races than see effort put into a joke race that shows up every once in a blue moon.
