Removed attack_paw, attack_animal and attack_slime.
Readded monkey dexterity checks in each attack_hand as appropriate.
Readded interactions for slimes and monkeys using attack_generic proc.
Fixed some issues with previous commits, gave aliens and animals an attack proc, removed now-unused stungloves from attack_hand procs.
Fixed up weird sound-playing by simple animals, changed all simple animal attack strings to past tense so they gel with other harm intent actions. Readded simple_animal eating food, tested everything.
