-tg- Life() refactors

This commit does a *lot*
Main points of shit changed:
 - Breathing for carbons is now partially handled at a carbon/Life()
   level; Humans still use their species bullshit and all.
 - Most shit has been pushed up the chain to living/Life().
 - Simple_animals no longer use the fucking stupid Die() proc, they use
   death() like a consistant fucker.
 - Human vision is now handled via species.
 - Lots and lots of robot copypasta cleaned
  - AI is still a terrifying mess, not even -tg- touches it

I have tested this, and everything I thought to test worked:
 - Aliens breathing
 - Humans breathing
 - Human vision
 - Robot HUD
 - human HUD
 - Simple animals automatic systems
 - Simple animals dying properly
 - Robot goggles working
