    window: add notifications for sidebar operations
    
    Recently we removed gtk+ notifications from mount operations in the
    gtk+ sidebar in order to move the handling of those to Nautilus.
    
    Now that that is done, implement notifications handling for unmount
    sidebar operations. The mount operations notifications are still handled
    by gnome-shell, we will see if that continues making sense or not.
