Add minimal XRandR support to dummy driver

I would be extremely useful for the dummy driver to have minimal XRandR support, so we could use it to run automated tests in gnome-settings-daemon.
For the power plugin, we'd use XRandR DPMS support (to turn the screen on/off), and the backlight property (to change the backlight).
