added new backend method to get the component given a UID.

2001-08-09  Damon Chaplin  <damon@ximian.com>

	* pcs/cal-backend.c (cal_backend_get_object_component): added new
	backend method to get the component given a UID.

	* pcs/cal-backend-file.c (cal_backend_file_get_object_component):
	added implementation of above virtual method.

	* pcs/query.c (match_component): use the new backend function to get
	the CalComponent rather than the string. This avoids converting all
	the calendar components to strings and parsing them back into
	components for every query! (That wasn't a good idea, was it ;)

	* gui/e-week-view.c:
	* gui/e-day-view.c: use a timeout handler to layout the events,
	to avoid doing a layout for each event we get from a query.

	* gui/print.c (print_day_add_event):
	* gui/e-day-view.c (e_day_view_add_event): set start_row_or_col and
	num_columns to 0. They are guint8's.

	* gui/e-week-view.c (e_week_view_free_events): hide all the jump
	buttons. Fixes bug #5946.

	* gui/calendar-commands.c (calendar_set_folder_bar_label): added the
	day numbers for the month view.

	* gui/dialogs/recurrence-page.glade: changed "_Delete" to "_Remove",
	since it clashed with "_Add". Also added underlined accelerators for
	the recurrence radio buttons. Note that none of these accelerators
	actually work at present, due to the way we are using .glade files
	for each notebook page. I need to add a bug about this.
	Also, the "_Action" menu doesn't popup when I press Alt+A, even though
	the "_File" menu does popup when I press Alt+F. Strange.

	* pcs/cal-backend-file.c (cal_backend_file_get_timezone_object):
	removed debug msgs.
