Coats!

Adds a bunch of coats (navy, burgundy, charcoal, black, black with suit jacket) and a special contraband one, all with original-ish sprites (it used a  Nienhaus's Tweed Jacket as a base, but was heavily edited), icons and code, added to the coat vendor and playtested.

I may do closed variants later if I can be arsed.

A bunch of screens:

They are all based on the same single coat, so aside from the coatraband one which is a bit more edited and the jacket variant, which is just regular black coat overlaid on a recolored IA jacket, they all look the same shape-wise.
Add urist to the path after wizard, and profit. Currently, these won't show up on the mob.
