Added datum mutations

Also removed some mob vars like sdisabilities and merged the usability
with disabilities
Removed need for mutations var, they are now handled in dna
Removed blinded var, now its handled by eye_blind being bigger than zero
Ands lots, lots of other shit in files that used mutations

THIS IS NOT FINISHED, WORK IN PROGRESS, DONT JUMP ON IT
You should probably return if this happens, or maybe drop the dualsaber entirely? Since you're nerfing them to no longer work with hulks at all, not even with no defense, and the way it is right now lets them use those as usual, but only if they don't drop them.
