    Update selection when a box is removed or inserted
    
    When deleting a box, the selection count in the topbar isn't updated
    correctly. This patch makes sure the selection is notified when an
    item is removed or inserted from the model.
    
    (fixme later, libgd-way isn't as nice as having a real
    GtkTreeSelection::changed)
