- Added Stelladaptor support for joysticks and paddles. Since I don't

yet have a driving controller, I can't add support for it (donations would
be welcome :)

 - The buttons/axis events seem to work, but I really have to push
hard on the sticks for an event to register.  It's probably because of
the crappy controllers I have.  I'll test on a real 2600 when I get a
chance.
