fix github issue #745 - two-weapon paralysis

Issue #745 by k2:  when using two-weapon combat, the second attack
would still take place even if the first attack caused the hero to
become paralyzed (hitting a floating eye or g.cube).

Cleaver's up-to-three attacks had the same problem but did stop if
the hero underwent life-saving after some fatally damaging counter-
attack.  Two-weapons didn't.  Make them both stop early if either
paralysis or life-save occurs.

Multiple attacking monster against monster and against poly'd hero
already deal with paralysis; life-saving doesn't apply.

Fixes #745
