More work on CentCom.

CentCom Special Ops shuttle updates.
Removed gib implants from SS13 until we figure out what to do with them.
They are now located on CentCom for a future revision.
Added air alarms to Fore Primary Hallway.
Disintegrate now leaves different remains for robots and aliens.
Misc fixes.
