calculate the work week, week, and month views more exactly

2004-06-09  JP Rosevear  <jpr@novell.com>

	* gui/gnome-cal.c (get_times_for_views): calculate the work week,
	week, and month views more exactly
	(update_adjustment): update the view based on week view scrolling
	(setup_widgets): listen for the scroll bar moving on the week
	views
	(gnome_calendar_update_date_navigator): adjust for compressed
	weekends in the month view
	(gnome_calendar_on_date_navigator_selection_changed): ditto

	* gui/e-week-view.h: add protos

	* gui/e-week-view.c (time_range_changed_cb): calculate the
	base_date and first_day_shown more simply, allows multi-week
	selection to work better; update the base date when told to do so
	(e_week_view_init): init update_base_value var
	(e_week_view_get_update_base_date): accessor
	(e_week_view_set_update_base_date): ditto
