set "sort_info" on our sorter when we get a new sort_info to keep things

2000-12-07  Chris Toshok  <toshok@helixcode.com>

	* e-table.c (e_table_set_state_object): set "sort_info" on our
	sorter when we get a new sort_info to keep things in sync.

	* e-table-sorter.c (ets_set_arg): new function, allowing the
	setting of "sort_info".
	(ets_get_arg): new function, allowing the getting of "sort_info".
	(ets_class_init): fill in GtkObject::set_arg and get_arg.
	(ets_sort): set ets->needs_sorting to 0 so we don't sort
	unnecessarily.
	(e_table_sorter_model_to_sorted): we may have ets->backsorted (and
	should use it if we do) even if we didn't need to sort.
	(e_table_sorter_sorted_to_model): same, except ets->sorted.
