renaming shopkeepers and priests

     From a bug report, the 'C' command wasn't reporting that
"<shopkeeper> doesn't like being called names" even though the user's
supplied name was ineffective.  Same thing for temple priests and other
minion monsters; the name was accepted but didn't do anything.  Make such
monsters reject new names.
