Brightness control widget

[LBCrion]

Is there any interest in a brightness control widget for sfwbar? It will be fairly trivial to implement and looking around it seems that it's a feature people generally want. The question would be what format it should take (a slider?) and where it's best to place it.

A light bulb as a widget icon would be great addition adjacent to the volume indicator. My level indication preference is typically numeric (%) based for simplicity, or you can use a grayscale gradient (black->gray->white).
