* Fixed BView::_SetShelf(), it did not remove a previous shelf.

* Fixed BShelf::_AddReplicant(), at least a bit. I managed to add the "ScreenChanger"
  icon to the tray, although the icon was not drawn, and it was on the wrong
  position.
* _AddReplicant() also did not reply to the waiting message source in case
  of failure.
