check for an attendee in the list (comp_to_list): only add the user if

2002-08-08  JP Rosevear  <jpr@ximian.com>

	* gui/itip-utils.c (users_has_attendee): check for an attendee in
	the list
	(comp_to_list): only add the user if they aren't on the list
	(comp_server_send): don't remove the users, pass back the list
	(itip_send_comp): send to server before doing comp_minimal

	* gui/dialogs/comp-editor.c (real_send_comp): edit and save the
	updated comp

	* pcs/cal.c (impl_Cal_send_object): copy the correct item to pass
	back
