fix github issue #155 - encumbrance vs water

Fixes #155

When drowning, you need to be unencumbered in order to crawl out of
water.  When not drowing, you don't, but put a limit on how much can
be carried.  If polymorphed into a swimming creature, allow stressed
or less; otherwise (magical breathing), burdened or less.  (Doesn't
apply on the Plane of Water since there's no climb from water to land
involved.)
