reconcile toss_up() with hmon_hitmon()

Throwing silver or blessed non-weapons upward and having them fall
back onto susceptible hero's head wasn't adding the extra bonus damage
that a weapon would get in that situation.

Make hitting vulnerable monsters with blessed just-about-anything get
the 1d4 bonus that blessed weapons get for that.  Doesn't apply to
things that have their own special handing, like potions or eggs.
