prayer fix for being in poison gas cloud region

Browse Source 
Like stuck-in-wall, there might not be any place to move the hero
in order to escape a poison gas cloud.  That could result in "fix
all troubles" becoming stuck in a loop.  3.6.something fixed the
stuck-in-wall case by temporarily conferring Passes_walls.  Fix the
in-poison-region case by temporarily conferring Magical_breathing.

Not adequately tested...

I don't think that this fixes "#K4252: NH 3.7 Prayer Bug" where the
game hung during a couple out of scores of prayers.  I didn't see
any other fix-trouble cases that seemed likely to remain unfixed
and end up with repair attempts retrying.
