Code effeciency project:  handle_environment (human/life())

Before:  We process a whole lot of bullshit for no real reason most of the time because temperatures are perfect.

Now:	 We check if our temperatures and environment are within normal bounds and get the hell out of the proc.

Also:    Mobs that are long dead or just dead mobs spawned at round start won't process Life(), those 3 clowns don't need Life(), those jerks.
