[gnome-shell] st-bin: Delegate popup-menu signal to child if we have one

[Jasper St. Pierre <jstpierre src gnome org>]

commit 660b801775b9a58428def543edb541e882bf1167

    st-bin: Delegate popup-menu signal to child if we have one
    
    This makes it much easier to implement correct popup-menu behavior
    in the case of nested bins.
    
    This fixes the context menu key in application search results when a
    result has focus.
