Commiting for the night, in case KGB steals my laptop.

Pretty much finished surgery system.
-working appendectomy, bone surgery, eye surgery, face surgery, brain surgery (humans only) and metroid core surgery.

-moved operation stages tracking vars to one op_stage datum. Left brain opstage var alone because way too many things reference it.

-added bone gel and bone setter.

-added check for surgery tools, so new doctors won't beat shit out of patients on optable too often.

-pretty much emptied surgery_tols.dm, it was unneeded by this point.

Still need to test it more, slap sanity checks everyfuckingwhere.
Also more literate messages written with help of trained monkey (faux).
