Bug 1150742 - Move new_tablet_ic_menu_forward -> ic_menu_forward. r=mhaigh

This involved removing drawable-large-v11/ic_menu_forward.xml, which
was a null reference presumably there to save memory when the
browser_app menu loaded the forward menu item. Also, the
new_tablet_ic_menu_forward null reference for API 9 builds was
removed.
