Set alpha when disabling button

[natanrolnik]

I noticed that calling the roundedButton.isEnabled = false doesn't dim it - which is the case in other UIControls.

I noticed that in all setters _isDirty = YES; [self setNeedsLayout]; are called, and thought about using the same pattern; however, there is no need to layout all the subviews again, so I thought setting alpha directly a more reasonable solution.

Aha. I didn't even think about the enabled state. Thanks so much for that!
