Add an endgame to the hunt

When the last target image is found, the following things will now
happen (after a 10-second delay):

  1. Coda will comment on all of the target images noting that Zombo
     is weak, (this will bring them to the top on the next refresh).

  2. A new image will appear of Coda in a non-apocalyptic future

  3. Coda will comment on that final image, wishing the boys luck.
