    gtkentry: Add a "catchall" click gesture handler
    
    This gesture is set on the whole widget surface, since there's
    multiple input targets inside an entry (icons, the GtkText itself)
    it makes sense to consider the full entry an area handling clicks.
    Ensure these events don't propagate further up, and result in other
    actions.
