Notifications in Phone (part 1)

- Added StatusBarNotification class to handle notifications
- StatusBarNotification has tons of copied comments from
  NotificationMgr.java.  Also has minimal code to make the notification
  pop up (without call-specific data).
- Moved the UI start-up code from InCallPresenter to
  StatusBarNotification.  Incoming phone calls need to display an alert
  above immersive (fullscreen) foreground activities and the way to do
  that is through notifications.  The old phone app did the same
  thing...finally bringing over that functionality.
