Terribly sorry for taking so long to get this out....
This is the first patch to xnlock.  Changes include:

    o  full pathname for "fortune" program.
    o  removed annoying "test" where little man walks from button click
    o  cursor is now invisible

I'd still like to remove the need for XGrabServer().  If someone has
suggestions, I'd love to hear them.
