 - DialogFragment was removed and just use the dialog-themed activity
   instead.  The previously GrantPermissionFragment, now acts as a
   helper class.
 - The dialog always tells the window its the same size, but then
   draws at whatever height is required for the current permission.
   (this allows it to stay in one position)
 - Touching outside now does nothing so that the user must respond
   to the permission request.
