Add a screen saver mode to the main menu

If you press RED (F1) while on the main menu it will toggle on/off the screen saver mode which simply hides everything except the background of the screen. Useful if you want to use a video background or slide show as a screen saver

You can also mute the background video audio by pressing GREEN (F2)
