jabberwock hands

Revert a change from five weeks ago which added M1_NOHANDS to the
jabberwock definition.  The jabberwock illustration from Lewis Carroll's
_Through_the_Looking_Glass_ depicts one with its forelegs held like arms
and the forefeet look like clutching hands.  Enormous hands, but
nethack's one-size-fits-all object model means they can manipulate things
just like anybody else's hands.
