#393 Rename and move the treasurelist for human bodyparts

[DraugTheWhopper]

This pair of patches renames the human_parts treasurelist to humanoid_parts, and moves it to it's own .trs file.

The goal is to eventually move most humanoids to use this treasurelist for bodyparts, including things like goblins, giants, trolls, etc.

One possible gotcha is that if a server has a persistent map or playerfile which references this treasurelist, it may break. I don't think this should be a problem though. If a server admin is paranoid, they could grep all persistent player and map files for the original string.

Applied as r22098 (arch) and r22099 (maps), thanks :)
