Subject: [PATCH] New top-level Dock in Settings and a Dock Settings screen
 with Audio item. #2367275

Add a new top-level setting for car/desktop dock settings.
Sub menu contains one item - Audio (settings)
Sub text for Audio shows current docked status and launches either the
 audio settings or a dialog saying that you're not docked and you need to
 buy a new dock from Google (kidding).
