PatR 6c0f92a264 end of game oddities: thrownobj, ball&chain ...

If you died while Punished but with attached ball and chain temporarily
off the map (changing levels and when swallowed are the cases I looked
at; there may be others), the ball and chain objects would not appear
in bones (for the falling-down-stairs case; bones are never saved if
hero dies while swallowed) and they weren't being freed.  Put them
back on the map so that they'll be included in bones and also freed as
part of normal map cleanup.

This caused a problem if the attached ball had state OBJ_FREE due to
being thrown rather than being temporarily off the map.  'thrownobj'
was being deallocated without first cancelling punishment, so uball
object was freed via thrownobj pointer but stale uball pointer still
referenced it.  Unpunishing would introduce sequencing issues because
that would need to be after attribute disclosure.  So instead of
deallocating thrown or kicked object, put it/them (can't actually have
both at the same time) back on the map.  This has a side-effect of
saving thrown Mjollnir in bones if it kills hero when failing to be
caught upon return.  (I thought that that had been fixed ages ago?)
