Use CalComponent instead of iCalObject. Work around not having a compare

2000-08-20  JP Rosevear  <jpr@helixcode.com>

	* gui/e-week-view.c (e_week_view_update_event): Use CalComponent
	instead of iCalObject.  Work around not having a compare
	dates routine for two CalComponents.
	(e_week_view_reload_events): Use revamped CalClient
	(e_week_view_reshape_event_span): Use CalComponent instead
	of iCalObject, #if some alarm stuff
	(e_week_view_update_event_cb): Use CalComponent instead of
	iCalObject
	(e_week_view_foreach_event_with_uid): ditto
	(e_week_view_remove_event_cb): ditto
	(e_week_view_free_events): ditto
	(e_week_view_add_event): ditto
	(e_week_view_on_editing_stopped): ditto
	(e_week_view_find_event_from_uid): ditto
	(e_week_view_key_press): ditto
	(e_week_view_show_popup_menu): ditto
	(e_week_view_on_new_appointment): ditto
	(e_week_view_on_edit_appointment): ditto
	(e_week_view_on_delete_occurrence): ditto
	(e_week_view_on_delete_appointment): ditto
	(e_week_view_on_unrecur_appointment): ditto

	* gui/e-week-view.h: Update prototypes.
