Remove player critters.

[Drago156]

I have to pretty much agree with SRQ, I've been killed as antag by a mouse before and the best response I got about why was that someone said, "if they know you're an antag, they can attack you." not sure how reasonable that is by admins, but it seems pretty fucking rude to do. As well, ghost critters don't really serve much of a purpose except to allow dead people to annoy others, complete staying alive and escape goals, and possibly ruin antag kill objectives and definitely antag escape alone objectives.

I vote to remove ghost critters, polymorphs are still good though.
