\#wizkill fix

When running #wizkill, if hero was swallowed and you killed the
engulfer and that dropped hero onto a level teleporter, the targetting
loop for selecting the next monster to kill kept going after changing
to another level.  Terminate #wizkill if killing something sends you
to a different level.

Not fixed, and an old bug, or variation of one:  the cursor got
positioned at the coordinates of your spot on the prior level even
though the part of the new level where you actually arrived was
displayed.

The hack.c and trap.c bits are just reformatting.
