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
Monkey issues with lack of animation were in humanize proc
WIthout this any mutations check after race change would runtime due to original mob being deleted, this way i just switch the mob mid-way based on return of transformation proc
