Acknowledge Schroedinger's cat (trunk only)

Acknowledge Schroedinger's cat at end of game.
- determine cat's status:
      - give points for the animal which accompanied
        you.
     or
     - include dead cat in the box contents.

Schroedinger's cat is the only ordinary creature
that could actually ascend with you.

This patch doesn't deal with any supernatural creatures
including:
 - djinn in bottles
 - ghosts in bottles
