	* libecal/e-cal.[ch] (e_cal_get_objects_for_uid): new function
	to retrieve objects and detached recurrences for that object.
	(e_cal_get_object): deal with the backend returning a VCALENDAR
	object. In that case, just get the first component of the same
	type we are using.
	(generate_instances): when we have an UID, use the new function
	e_cal_get_objects_for_uid, avoiding countless calls to
	e_cal_get_object_list.

	* backends/file/e-cal-backend-file.c (e_cal_backend_file_get_object):
	if we have detached instances, return a VCALENDAR with the master
	object and any detached instance.
