Introducing the PreferenceDrawerActivity which makes use of the new navigation drawer UI google has introduced in updates to many of their apps.  This relies on headers which are displayed in the drawer and preference fragments as the main content.

Patch Set 2:
  Create drawable backgrounds for the drawer.

Patch Set 3:
  Only access the action bar if it is not null.  The setup wizard does
  not have an action bar and will cause settings to receive a NPE.
