eating corpses while hallucinating (trunk only)

Contributed by <email deleted>, give an
alternate message when eating a corpse while hallucinating, including one
that gives homage to Tony the Tiger from old Frosted Flakes commercials
if you happen to be polymorphed into a tiger.  Even players who try to
keep their characters hallucinating all the time are unlikely to ever run
into "tastes gr-r-reat!".

     I rewrote the conditional expression to only test Hallucination once.
And I added the comment about omnivores, who'll never get "is delicious"
result with the current carnivore vs herbivore logic.  (That behavior has
been around for quite a while, but seems somewhat suspect.)
