The following is a fix for the ring of protection from shape changers.
The problem is that, if one is swallowed by a chameleon masquerading as
a trapper, and then one puts on a ring of protection from shape
changers, one instantly dies because of it, since you are now inside a
non-swallowing monster.  I figure that if you put on a ring to protect
you from a monster, it shouldn't make that monster kill you.  Here is a
context diff which fixes this problem.
