prime_mate TRIED TO GO TO INVALID STATE refuse

Prime mates have a trader component and and code that looks like it was copied from pigs. There are checks for accepting meat (even though they can't eat it,) and becoming a follower (even though they lack the follower component!) Failure sends the prime mate to the refuse state, which it doesn't have.

There's some code commented out for accepting weapons. The code for accepting hats actually works somewhat, and they'll drop their hat to put on a new one (even though it looks like it's supposed to fail if they already have one.)
