fixes entry for PR #978 - suppress monster's name

for <new form> portion of messages "<old form> turns into <new form>"
to avoid named vampires yielding "Dracula turns into Dracula".

Pull request from entrez:  a couple of engulf messages used regular
monster naming for vamp-shifters transforming rather than dying.
3.6.1 had fixes for this for basic monster death but didn't handle
engulfing.

Fixes #978
