Fix a couple of weird messages issued when a shape-shifted vampire
is "killed" and reverts to regular vampire form instead of dying.
First weird one was when vampire has been given a name, as reported.
Second was noticed while fixing that: when cause of death destroys
the creature so thoroughly that there'd be no corpse, the alternate
phrasing for noncorporeal or amorphous form should be used.
old:
The Dracula suddenly transforms and rises as Dracula!
The vampire bat is disintegrated. The seemingly dead vampire bat
suddenly transforms and rises as a vampire!
new:
Dracula suddenly transforms and rises as a vampire!
The vampire bat is disintegrated. The seemingly dead vampire bat
suddenly reconstitutes and rises as a vampire!
