Unconditionally remove the client from the alarm notification system.

2001-01-01  Federico Mena Quintero  <federico@helixcode.com>

	* gui/gnome-cal.c (gnome_calendar_destroy): Unconditionally remove
	the client from the alarm notification system.
	Removed all the obsolete alarm code.

	* gui/event-editor.c: Removed some crufty externs left over from
	Gnomecal.

	* gui/calendar-commands.c: #include "goto.h"
	Removed crufty variables left over from Gnomecal.
	(new_calendar): Do not take a full_name parameter.
	(init_username): Removed function.
	(init_calendar): Wheeeeeeee!  Removed crufty function.
	(quit_cmd): Removed function.

	* gui/print.c (WEEK_STARTS_ON_MONDAY): Made it unconditionally
	FALSE because we do not use the configuration setting anyways.
	Sigh, all the printing code needs to be revamped.
