[Matthew Barnes <mbarnes src gnome org>]

commit ebcb25def12302eca4c79e995533bb7a19be4a01

    Remove e_tree_save_expanded_state_xml().
    
    Reducing API bloat.  Do this instead:
    
      adapter = e_tree_get_table_adapter (tree);
      xml = e_tree_table_adapter_save_expanded_state_xml (adapter);
