swallowed time (trunk only)

From a bug report, making engulf time longer for high AC
didn't make sense for non-digestion attacks:  taking longer to die from
being digested (high AC lets you last longer there) is much different from
being stuck inside a vortex or elemental and suffering extra buffettings
or whatever.  Calculate swallow time differently for non-digestion than
for digestion.  (The adjustment based around level 25 doesn't make much
sense either, but I left that in.)

     If you survive total digestion via life saving, you get a message
about the monster not liking your taste.  I don't think that's appropriate,
but haven't tried to figure out how to fix it.
