Expanding CarDrawerActivity for nested navigation

- CarDrawerActivity now works with CarDrawerAdapter and subclasses to
  display Drawer content. It includes a CarDrawerController that handles
  nested navigation (it maintains a stack of CarDrawerAdapter's). Also
  added progress-bar that can be displayed while loading the content for
  next level of drawer items.
- Added CarDrawerAdapter and sublcasses CarDrawerListAdapter and
  CarDrawerEmptyAdater for use by consumers of CarDrawerActivity.
