IPCs, prosthetics, suits

Fixes suit cooling units so they no longer have infinite power.  Made
their batteries last much longer, too.

Anom suits can now hold suit coolers.  Softsuits can now hold large o2
tanks.

Prosthetics now malfunction at brute+burn-11% chance so getting your arm
scratched doesn't turn you into humpty dumpty.

BSTs get a new verb to ruin everything.
