    Replace "interval updates" by consistent list->model mapping.
    
    The CLI config panel stored entries in
    ConfigPanel.confImportantContents which were regularly polled and
    exported to GUI treestore.
    
    This created problems with selections as the liststore was essentially
    emptied at each timeout.
    
    The new approach is to override ConfigPanel.confImportantContents
    with a wrapper class which maintains consistency between the Python
    list and GUI liststore at each append/setitem.
