wizard mode ^T

Noticed while testing the stair labeling, knowing the teleport away
spell (and without innate teleport ability--not sure whether that's
a factor), using ^T always attempted to cast the spell, even if you
used m^T to explicitly request wizard mode telport on demand.  Since
my samurai had no chance to cast such a high level spell, I couldn't
use ^T any more.

With a different character, I ended up with 15(2) energy after a ^T
attempt failed.  I've put in a fix for this but after the other one
I don't think it matters.
