[PR] Makes ghostcritters able to be picked up

[Luxizzle]

I'm okay with this PR in general, but I know it stems from an original and larger one to make people able to eat critters, which is something I am deeply, deeply disturbed by. If this stands alone, I think it's actually pretty cute to pick up critters and put them in pockets and on back slots--mentor and admin mice do some of this anyways!

But I don't like the idea of going down the path of having players being able to eat other living critter players or living critters in general, especially if they're other living critters that are able to struggle and stuff while they're being grabbed. It's too visceral and freaky for me. Sorry.

I think this PR is good on its own as a standalone, though.

That's gross and hope that's not true, I'm honestly already weirded out by the organ eating thing of lizards, since when you think about it, it's basically cannibalism.
