Add a curses gizmo for solving Sunday-paper-type cryptograms based on
substitution ciphers. It gets the cleartext from fortune. I wrote this
some years ago for my own amusement; a couple people have suggested
that I should import it.
Approved only by groo, so I'm going to wait a couple days to hook it
to the build in case anyone demands it be removed again...
