Basically, surgeries are now initiated by bedsheets or surgical drapes, and consist of separate steps.
Appendicitis is sort of hacky, but it should work for now. I'll update it when I add processing organs.
Added getbrain() and getappendix() procs, which can be used instead of checking the old (now missing) x_op_stage variables.
Added a surgical apron, using old sprites by matty.
Updated the map:
Removed the note with spell descriptions from the wizard's den for Kor.
Updated the operating room.
Updated xenobio to have appropriate tools for slime surgery.
