alright, 4-way manifolds, manual t-valves, pipe caps.
Added implant removal surgery.
If you fail the step, has small chance of activating implant.
Gives you a sound and ~15 ticks to run away like hell.

Changes I did to other parts to make this possible:
-Implants are now organ-based, not mob-based
-Part of implant working code is moved to appropriate activate() procs
Got rid of evac part lights. No fun allowed.
Also forgot to change paths for lab coats in away missions, fixed that now.
