go slow and clear the map if the last uri and the current uri do not match

2001-12-19  JP Rosevear  <jpr@ximian.com>

	* conduits/calendar/calendar-conduit.c (check_for_slow_setting):
	go slow and clear the map if the last uri and the current uri do
	not match
	(post_sync): save the last uri

	* conduits/calendar/calendar-conduit-config.h: handle a last uri
	config option

	* conduits/todo/todo-conduit-config.h: ditto

    	* conduits/calendar/calendar-conduit.c (start_calendar_server):
    	use the open_default_calendar method

    	* conduits/todo/todo-conduit.c (start_calendar_server): same as above

    	* cal-client/Makefile.am: link with bonobo conf

    	* cal-client/cal-client.h: new protos

    	* idl/evolution-calendar.idl: make sure open method raises
    	appropriate exceptions

     	* gui/e-itip-control.c (start_calendar_server): use
     	cal_client_open_default_* calls

     	* cal-client/cal-client.c (real_open_calendar): do the real work
     	of loading
     	(cal_client_open_calendar): use above
     	(get_fall_back_uri): get the basic local uri
     	(get_default_uri): get the default uri from the config db
     	(cal_client_open_default_calendar): open the default uri or the
     	fallback if the method is unsupported
     	(cal_client_open_default_tasks): same for tasks
