Implement a user suggestion that tame humanoids should avoid eating
corpses of their own species. Prevent them--except for kobolds, orcs, and
ogres--from doing so unless starving. Arbitrary: tame elves won't eat
other elves even when starving. A polymorphed character will incur the
effects of cannibalism when eating either his/her underlying race _or_
the current one (player orcs and cavemen aren't affected though).
