Bar buttons inherit the 'separator' color if not opaque

[nickdaugherty]

If a bar button's color is not opaque, the separator color shines through and affects the button color, making it impossible to have transparent buttons. I know this is because the separator color is applied as the background color of a RelativeLayout in the xml...a better method may be to have a 1px element inside the relativelayout, to which the bg color is applied.

Agree, I have wanted to change this my self for a long time too. A patched for this would be welcomed.
