new proto and virtual method

2001-08-10  JP Rosevear  <jpr@ximian.com>

	* gal/widgets/e-canvas-vbox.h: new proto and virtual method

	* gal/widgets/e-canvas-vbox.c (e_canvas_vbox_real_add_item_start):
	adds the the item to the beginning
	(e_canvas_vbox_add_item_start): call the virtual method

2001-08-10  JP Rosevear  <jpr@ximian.com>

	* e-table.c (et_build_groups): add the items to the start or end
	based on where the click to add should be
	(e_table_setup_table): ditto
	(et_real_construct): read additional spec flag

	* e-table.h: new flag

	* e-table-specification.c (etsp_init): init new flag
	(e_table_specification_load_from_node): set click to add end flag
	(e_table_specification_save_to_node): write out flag

	* e-table-specification.h: new flag
