Impending joystick changes

Some joystick API changes:

    The joystick hat position constants have been changed:
    Old constant            New constant
    ------------            ------------
         0                  SDL_HAT_CENTERED
         1                  SDL_HAT_UP
         2                  SDL_HAT_RIGHTUP
         3                  SDL_HAT_RIGHT
         4                  SDL_HAT_RIGHTDOWN
         5                  SDL_HAT_DOWN
         6                  SDL_HAT_LEFTDOWN
         7                  SDL_HAT_LEFT
         8                  SDL_HAT_LEFTUP
    The new constants are bitmasks, so you can check for the
    individual axes like this:
            if ( hat_position & SDL_HAT_UP ) {
    and you'll catch left-up, up, and right-up.

I’ll be committing this to CVS very soon.

See ya!
