Title: Syntax simplification

Currently in rgbapng you need to do this : `rgba-background(rgba(black, .2))` which is clearly overkill. By adding as simple $opacity parameter, taking 1 as default, it all goes down to `rgba-background(black, .2)`. Because after all it's not like someone is gonna use rgbapng with something else than rgba().
