Add Corpse class and create_corpse factory
Corpse is a non-portable Container subclass that holds a deceased mob's
inventory. The create_corpse factory transfers items from the mob to the
corpse, sets a decompose_at timestamp for eventual cleanup, and calls
despawn_mob to remove the mob from the world.
