If the sort_info can't group, hide the grouping button and label.

2001-08-10  Christopher James Lahey  <clahey@ximian.com>

	* e-table-config.c (setup_gui): If the sort_info can't group, hide
	the grouping button and label.

	* e-table-header-item.c (ethi_header_context_menu): Removed the
	Group By This Field menu item if the sort_info doesn't support
	grouping.

	* e-table-sort-info.c, e-table-sort-info.h
	(e_table_sort_info_get_can_group,
	e_table_sort_info_set_can_group): Added these functions.

	* e-tree.c (e_tree_set_state_object, et_real_construct): Set
	can_group to FALSE for all our sort infos.
	(e_tree_get_state_object): Fixed a potential gtk_object_ref (NULL)
	here.
