Centralized marking of month items. We now have a little utility function

Centralized marking of month items.  We now have a little utility
function to colorify the days in a month item that have events
scheduled for them.  This is currently used by the year view and
the go-to dialog.  Fixed buglets here and there.

1998-08-29  Federico Mena Quintero  <federico@nuclecu.unam.mx>

	* mark.[ch]: New files with utility functions to mark calendars
	with their events.

	* mark.c (mark_month_item): New public function to mark a month
	item with events.
	(unmark_month_item): New public function to unmark all the days in
	a month item to their default appearance.

	* year-view.c (year_view_set): Use the new unmark_month_item() and
	mark_month_item() to mark the months with events.

	* goto.c (update): New function that updates the calendar in the
	Go-to dialog by marking the days.

	* timeutil.c (time_year_begin): Modified to take a time_t value.
	(time_year_end): Likewise.
	(time_month_begin): Actually implemented this function, which was
	in the header file but not here.
	(time_days_in_month): New public function that returns the number
	of days in a month.

	* Makefile.am (gnomecal_SOURCES): Added mark.[ch] to the sources.

	* year-view.c (unmark_days): Use unmark_month_item().

	* gncal-full-day.c (gncal_full_day_destroy): Fixed crash when
	destroying the full day view.  The full day's destroy method is
	unusual in that it destroys the list of child widgets itself, as
	it does not have a remove method, so it needs to reset the list to
	NULL.
