2002-10-24  JP Rosevear  <jpr@ximian.com>

	* gui/e-itip-control.c (init): initialize new values
	(clean_up): free new values
	(find_my_address): if we have a delegator address, use it instead
	(write_html): display delegator info to user
	(show_current_event): if we have a calendar uri, use that and
	describe the event differently
	(show_current_todo): ditto
	(show_current): search for delegator X properties
	(e_itip_control_set_delegator_address): accessor
	(e_itip_control_get_delegator_address): ditto
	(e_itip_control_set_delegator_name): ditto
	(e_itip_control_get_delegator_name): ditto
	(e_itip_control_set_calendar_uri): ditto
	(e_itip_control_get_calendar_uri): ditto

	* gui/e-itip-control.h: add protos

	* gui/itip-utils.c (comp_from): use the first attendee as the from
	address for things other than request, cancel and add (use
	organizer) and publish (use default address)
