Today: Beautification of the Preferences dialog. Made the menus more

Today:  Beautification of the Preferences dialog.  Made the menus more consistent
with the rest of GNOME.  Started work on the meat of the month view.  Minor fixups
on some of the other views.

1998-08-24  Federico Mena Quintero  <federico@nuclecu.unam.mx>

	* prop.c (build_two_radio_group): Doh.  Set the state of the radio
	buttons properly.

	* month-view.c (month_view_time_format_changed): New public
	function that notifies the month view of a time format change.

	* gnome-cal.c (gnome_calendar_time_format_changed): New public
	function that notifies the calendar of a time format change.

	* main.c (time_format_changed): Use gnome_calendar_time_format_changed().

	* month-view.c (month_view_update): New public function to update
	the month view when an event changes.  This is still unfinished.
	(month_view_set): New public function to set the month in the
	month view.

	* gnome-cal.c (gnome_calendar_direction): Add case for month view.
	(gnome_calendar_set_view): Likewise.
	(gnome_calendar_update_all): Likewise.

	* timeutil.c (time_add_week): Implemented the time_add_week()
	function, which was on the header file.
	(time_add_month): Added public month-adding routine.

	* gnome-cal.c (gnome_calendar_get_current_view_name): Add case for
	month view.
	(gnome_calendar_goto): Likewise, and set the time on the month view.

	* month-view.c (month_view_new): Now it takes the calendar plus
	the time_t representing the month.

	* gnome-month-item.h: Added documentation on the object arguments
	for the month item.

	* month-view.c (month_view_init): Added a month/year heading to
	the month view.

	* TODO: Updated the TODO list a bit.

	* main.c (gnome_cal_file_menu): The preferences menu option should
	go in the File menu.
	(gnome_cal_edit_menu): Added stock pixmaps to the menu items.
	(gnome_cal_menu): Renamed the Calendar menu to Edit.
	(gnome_cal_help_menu): Use "About Gnomecal", not just "About".

	* prop.c (hour_activated): Notify the property box that it has changed.
