Make genetic instability scale according to the mutations

[Daeren]

I left anaerobic at -40 because I thought it made you immune to choking, but at the very least I'm almost sure it makes you completely immune to suffocation damage, in the same way there's a mutation that makes you immune to toxic damage. That is a hell of an advantage when you factor in things like shock.

And honestly, I'm open to tossing stability out completely in light of my personal changes if it doesn't shake out, I just wanted to do a sanity pass on it since I figured I could do that on my own. New Genetics has mostly been ISN's project, and I haven't gotten a chance to chat with him about it yet.
