Clothing descriptors based on personal wealth

[WishingOnAWendy]

Setup the clothing descriptors on NPCs to be based on their personal wealth class

[ryceg]

To expand upon this, clothes should be tied to gender, profession, and wealth class. I envisage a getter (similar to the npc.descriptor getter) taking randomly from hat, torso, pants, shoes, and misc. Currently, we do not have living standards expressed as a feature (we have social class, but they are discrete concepts), so I'll be putting this on the backburner for now and removing the 'good first issue' tag.
