pull request #768 - log declined wish or genocide

Pull request from vultur-cadens:  if a wish is declined by asking
for "nothing" or "none" or "nil", log that for gamelog/livelog as a
declined wish.  Likewise when specifying monster species or class to
genocide as "none" or "nothing" or ESC, log it as declined genocide.

Closes #768
