Subject: [PATCH] Enable RTL support on LeftButton

By default RTL is not enabled on the MaterialMenuDrawable of which the LeftButton extends. This results in the back button not being flipped when running your app against a right-to-left language. Enabling RTL for the LeftButton fixes this behavior and correctly flips the button when needed.
