        (manager_changed_cb): Notify our listeners if we get a changed
        signal from our manager.

        * gui/component/select-names/e-select-names-manager.c
        (e_select_names_manager_class_init): Added a "changed" signal".

        (section_free): Disconnect the changed handler.
        (e_select_names_manager_add_section_with_limit): Connect to the

        (e_select_names_manager_add_section_with_limit): Added.
        (e_select_names_manager_add_section): Changed to just be a special
        case of e_select_names_manager_add_section_with_limit.

        model is "full".
        (e_select_names_model_insert): Check that we aren't at the
        limit before inserting.  Silently return if we are.
