Removes redundant surgery for brain and eye repair, now covered by organ repair in general.

Attempted to limit regular surgery to non-robotic limbs and added surgical steps for robotic limbs.
Readded checks for smoking reagent transfer.
Fixes, oversights, tweaks with IPC.
Added some reagent bypassing for NO_BLOOD and some checks to various affect_touch() calls for NO_SCAN/IPC.
Added prosthetic-scanning functionality to cyborg analyzer.
Added prosthetic analysis to the robot analyzer.
Allowed people with internal cells to charge in robot chargers (IPCs).
