open task lists asynchronously. (client_cal_opened_cb): callback from the

2004-06-07  Rodrigo Moya <rodrigo@novell.com>

	* gui/e-tasks.c (e_tasks_add_todo_source): open task lists
	asynchronously.
	(client_cal_opened_cb): callback from the client when opened.

	* gui/gnome-cal.c (client_cal_opened_cb): disconnect from all
	signals of the client when opening it fails. Clean up the status
	messages correctly, based on source type.
	(open_ecal): for tasks, use e_calendar_table_set_status_message
	not e_calendar_view_set_status_message.
	(gnome_calendar_remove_source_by_uid): call update_query only when
	removing calendars, not tasks lists.
	(update_query): set meaningful status messages.
