Active mutation expansion/bugfix

This makes a few more mutations Active: the Retractable Claws, Insect Wings, and combat tails.  Also fixes #8959.

And player::suffer will need some love.  Sorry, folks, the flood of new mutations just got pushed back again.
From my experience with both CBMs, the time after them is activation time, they stay active forever (and being energy-sources, even if you zero out on power) after you spend so-and-so turns to activate them.
