Code Effeciency project:  mob_controller / human and monkey Life()

Summary:  Before we did a bunch of bullshit (cycle through every single external organ each tick processing it when we could preprocess it and be so much cheaper), we can also check to see if we're in a normal environment and if so, don't even bother processing the various checks for if we're hurt by it or not., did some fixes on monkey/Life() then turned around and fixed handle_virus_...something() in both human and monkey.
