Fixes entry for pull request by entrez. If poly'd hero is wearing
an amulet of magical breathing, avoid gradually losing hit points
while out of water when in aquatic form. You won't be able to put
on an amulet of magical breathing if already in aquatic form, but
you could have one carry over from being worn in some other form.
Implemented for monsters too but won't have any effect during play
for them because they never use that particular type of amulet.
Closes #635
if #untrap monst-from-web failure happened while hero was standing on a spot
where a new web couldn't be created (furniture, grave, magic portal),
the expected "<monst> remains entangled" feedback wasn't delivered
+if hero is wearing an amulet of magical breathing and polymorphs into a fish
+ or sea monster, don't lose health for turns spent out of water
