Hallucination vs gaze attacks (trunk only)

Browse Source 
Suggested by <Someone> in March, 2005 based on newsgroup discussion
at the time:  hallucination protects against touch of death attack by
disrupting how the hero's brain reacts, so why not against gaze attacks
too?  This gives hallucinating hero 75% chance of being unaffected by
gazes.  If unaffected or if the gazer has been cancelled, the gaze will
fail with some feedback.  Previously, all cancelled gazes failed but only
Medusa's gave feedback.

     This will give players another way to defeat Medusa, but since it
isn't foolproof and there are several sure fire ways already, I don't
think it'll hurt play balance there.  It may be useful to avoid getting
repeatedly stunned by Archons though.
