use ical partstat, role, cutypes directly

2001-09-13  JP Rosevear  <jpr@ximian.com>

	* cal-util/cal-component.h: use ical partstat, role, cutypes
	directly

	* cal-util/cal-component.c: ditto

	* gui/e-itip-control.c (find_my_address): set my addresses if the
	addresses match
	(find_attendee): strstr returns non-null on a match
	(write_html): use new icon, select the name displayed (organizer
	or attendee) based on method,
	(ok_clicked_cb): when rsvp'ing strip off all but the attendee
	being replied for as is specified in the spec
	(find_attendee_partstat): new util function to extract the
	partstat of an attendee
	(update_attendee_status): updates the partstat of a specific
	attendee in the reply message

	* gui/dialogs/meeting-page.c: use ical partstat, role, cutypes
	directly
	(popup_delegate_cb): if we delegate, notify of needs send and
	changed
	(popup_delete_cb): notify of needs send and changed for each
	deletion
