fix bullwhip-induced panic

Browse Source 
While testing some corpse/statue name manipulation changes I managed
to trigger a panic during end-of-game cleanup.  Using a bullwhip to
snatch a wielded cockatrice corpse from a monster's inventory into
the hero's inventory and being turned to stone due to lack of gloves
took the corpse out of the monster's inventory but didn't place it
anywhere.  If no life-saving took place, it led to an "obj_is_local"
panic during timer cleanup when freeing the level.

This patch includes some of the stuff I've been testing rather than
just the fix for the panic (which is the very last bit of the diff).
