Title: Enable overriding ActionBar alpha value

First of: thanks for this awesome library!

This change makes it possible to override the currrent alpha value of the ActionBar. The main purpose is being able to complete fade in the ActionBar whenever the NavigationDrawer slides in and fade it back to it's original state when the drawer slides back out. This is the same behavior as in the Play Music app.
