    omnibar: add IdeOmniBarRow::configure event
    
    Because we cannot activate actions from the parent via a popover, we need
    to propagate the event back up to our omnibar widget (who can then activate
    the proper GAction).
    
    This can be simplified by simply going to build-tools.configure('foo')
    detailed action-name once bug 768023 is fixed.
