added changed flags and added calls to a new function

2000-12-11  Damon Chaplin  <damon@helixcode.com>

	* gui/event-editor.c: added changed flags and added calls to a new
	function event_editor_set_changed() to set & reset this flag.
	Added prompt_to_save_changed() which is called when the user
	selects File/Close or the window's close button.
	Fixed the 'All day event' toggle button.
	Made the 'Alarm' page sensitive as appropriate when filling widgets.
	(Though note that the alarm widgets are not being set yet.)

	* gui/dialogs/task-editor.c: added changed flag as above.

	* gui/event-editor-dialog.glade: used good names for all the
	classification radio buttons so we can access them in the code.

	* gui/event-editor.c (init_widgets): use the "show week numbers" config
	option in the recurrence preview calendar.

	* gui/e-day-view.c (e_day_view_update_event_label): use 9:00 instead
	of 09:00 in the main view, as we do everywhere else now. It means the
	times won't line up, but they are easier to read which I think is
	better.
	Added support for Page Up/Down, though I think it should move the
	selection rather than just scroll the canvas.

	* cal-util/cal-recur.c (generate_instances_for_chunk): removed the
	end parameter since we should be using the chunk end time now.
	Added single_rule parameter for when we are generating the
	occurrences of a single RRULE, in which case the event's start date is
	not included in the occurrences output (unless it results from the
	RRULE expansion). Both of these fix problems when using COUNT.

	* gui/gnome-cal.c (gnome_calendar_on_date_navigator_selection_changed):
	fixed bug when checking if the new start day starts on the week start
	day. If you select a complete week it should now show the Week view.
