Changed the Properties menu item to Preferences. These are global

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

	* main.c: Changed the Properties menu item to Preferences.  These
	are global application preferences, not a single calendar's
	properties.

	* prop.c (prop_apply): Save the week_starts_on_monday flag to the
	configuration file.
	(properties): Added a check button for weeks starting on Monday.
	(properties): Beautified the Preferences dialog.

	* month-view.c (month_view_init):
	* goto.c (create_days): Set the month item to start weeks on
	Monday if appropriate.

	* main.c (init_calendar): A boolean is not an hour, so don't
	range_check_hour() on it.
	(init_calendar): Added a global week_starts_on_monday flag.

	* main.h: Added global week_starts_on_monday flag.
