Bug description:
  BACKGROUND

  Some months ago, while implementing the accessibility support for the
  Launcher I realized that the Launcher didn't emit properly the signals
  InputArea::OnStartFocus and InputArea::OnEndFocus, as was the parent
  the one emitting it.

  So Jay included the concept of the _enter_focus_input_area, the
  InputArea inside the BaseWindow that effectively would receive the
  keyboard focus, and Unity started to use it.

  CURRENT STATE

  But right now SetEnterFocusInputArea is not used at all on Nux, and
  although it is used on Unity (PlacesController and unityshell), the
  field that it sets "_enter_focus_input_area" is not used at all.

  In the specific case of the Launcher, it seems that gets/free the
  keyboard focus using GrabKeyboard/UnGrabKeyboard, and after a quick
  smoke test, it seems that removing that call doesn't have any effect.

  So I would suggest to remove that method, and update accordingly
  Unity, as it seems that is useless.
