## About The Pull Request
Implemented a bodypart texture overlay priority system - ensures that
derez suicide always goes ontop of carp infusions, and voidwalker curse
goes ontop of both - currently the last one applied is the one that
sticks with you. Also cleaned up duplicate update_body calls, either
removing them or adding ``update = FALSE`` to overlay code.
## Why It's Good For The Game
Having whichever overlay was applied the latest be displayed is just too
inconsistent. And duplicate calls eat perf, bad.
