OK, it seems that we have all the interesting properties for single-user

2000-07-26  Federico Mena Quintero  <federico@helixcode.com>

	OK, it seems that we have all the interesting properties for
	single-user calendars now.  RFC 2445 can bite me.

	* cal-util/cal-component.c (scan_property): Handle the RRULE
	property.  Yay!.
	(scan_recur): Likewise, yow!
	(get_recur_list): Likewise, yeehaw!
	(get_recur_list): Likewise, honk honk!
	(set_recur_list): Likewise, booooga booooga!
	(cal_component_get_rrule_list): Likewise, squeek squeek!
	(cal_component_set_rrule_list): That's it, I ran out of sounds.
	(cal_component_free_recur_list): Likewise.
	(scan_property): Handle the EXRULE property.
	(free_icalcomponent): Likewise.
	(cal_component_get_exrule_list): Likewise.
	(cal_component_set_exrule_list): Likewise.
	(set_period_list): Oops, free the old properties as well as
	removing them.
	(set_text_list): Ditto.
	(cal_component_set_exdate_list): Ditto.
