* Gives carbon/humans the proc/isonlifesupport() to replace the constant checks done in other areas. Returns 1 if the target is on life support, 0 if is not.
* Adds support for removing brains from mobs, without them dying. The installation of a brain into a body is still impossible at this time (looking to fix that, somehow).
* Adds an internal log to the advanced operating table, which keeps track of just about everything important done to it. This log can be viewed and wiped from the operating computer.
* Adds a blood syphon option, which becomes available when the advanced operating table gets emagged.
