Adding amputated leg items

[Kotlol]

This seems like a solid categorization, I'd honestly just merge 3 and 4, because technically *anything* can be taped to a leg, but that just means it's essentially like not having a leg, such as smaller objects.

No 4 is litterly items that don't work. Similiarly you cannot put certain items on arms either.
Mostly stackable items like paper.
