	These changes fix bugzilla bugs #874 and #875.

	* cal-util/cal-component.c (cal_component_get_exdate_list): Return
	a list of CalComponentDateTime instead of simple struct
	icaltimetype objects.  Exception date properties *can* contain a
	timezone parameter, so we need to include those if they are
	present.
	(cal_component_set_exdate_list): On the input, handle a list of
	CalComponentDateTime structures.  On the internals, handle a list
	of struct datetime instead of plain properties.
	(cal_component_free_exdate_list): Handle a list of
	CalComponentDateTime structures.
	(scan_exdate): Create a list of struct datetime structures.
	(free_icalcomponent): Free the exdate_list properly.

	* cal-util/cal-recur.c (generate_instances_for_chunk): Use the
	proper types for exception dates.

	* gui/comp-util.h:
	* gui/comp-util.c: New files with utilities for manipulating
	calendar component objects.
	(cal_comp_util_add_exdate): New function.

	* gui/Makefile.am (evolution_calendar_SOURCES): Added
	comp-util.[ch] to the list of sources.

	* gui/e-day-view.c (add_exdate): New convenience function to add
	an exception date to a calendar component.
	(e_day_view_on_unrecur_appointment): Use cal_comp_util_add_exdate().
	(e_day_view_on_delete_occurrence): Likewise.

	* gui/e-week-view.c (e_week_view_on_delete_occurrence): Likewise.
	(e_week_view_on_unrecur_appointment): Likewise.

	* gui/event-editor.c (nth_weekday): Be paranoid about valid
	position values.
	(fill_widgets): Use the proper types for exdates.
	(dialog_to_comp_object): Likewise.
