Give animals some equipment slots

[warcrimes]

and a hat slot.
also, since we have the handy dandy chest surgery update we know this is feasible-
1. drag critter (maybe only certain kinds like mice) onto operating table.
2. add box to critter's back
3. staple in place.
Critter now has a box for stuff. Use as courrier or suicide remote bomb.
Drawback: can't ignore doors anymore.
