RGB Redstone Dust

You know how in version 1.0, you must make your screen facing one direction only? You probably didn't because this update came out before the post even finished loading. But now instead of a thin panel on one side of the dust, a hollow cube surrounds it! As well as this massive change, all the colors have been made slightly more accurate, and the redstone dust levels now indicate brightness, 0 being black all the way to 15 being white.
