2004-12-18 James Bowes  <bowes@cs.dal.ca>

	* gui/apps_evolution_calendar.schemas.in.in: Add schema for Free/Busy
	template uri.
	* gui/calendar-config-keys.h:
	* gui/calendar-config.c: (calendar_config_get_free_busy_template),
	(calendar_config_set_free_busy_template),
	(calendar_config_add_notification_free_busy_template):
	* gui/calendar-config.h: Functions to get, set and monitor the
	Free/Busy template uri gconf setting.
	* gui/dialogs/cal-prefs-dialog.c: (template_url_changed),
	(setup_changes), (get_widgets), (show_fb_config):
	* gui/dialogs/cal-prefs-dialog.glade:
	* gui/dialogs/cal-prefs-dialog.h: Change 'Free/Busy Publish' tab to
	'Free/Busy'. Add an entry for setting the default Free/Busy uri.
	Only change the gconf setting on 'focus out' event
	* gui/e-meeting-store.c: (refresh_queue_remove): Check the hash using
	the attendee's mailto: address, rather than the memory address of the
	attendee object as the key.
	(e_meeting_store_get_fb_uri), (e_meeting_store_set_fb_uri): Get and set
	the EMeetingStore's Free/Busy template string.
	(process_callbacks_main_thread), (process_callbacks): Process callbacks
	in the main thread, so that widgets can be redrawn properly.
	(replace_string): Utility function for replacing wildcards in the
	default Free/Busy uri.
	(ems_finalize),	(ems_init), (freebusy_async), (refresh_busy_periods),
	(refresh_queue_add), (e_meeting_store_refresh_busy_periods): Add the
	ability to check for Free/Busy information from a default location,
	if all else fails.
	(start_async_read): Use gnome-vfs to read the Free/Busy information.
	* gui/e-meeting-store.h: Add function prototypes for get and set fb_uri
	* gui/e-meeting-time-sel.c: (e_meeting_time_selector_init),
	(e_meeting_time_selector_destroy), (free_busy_timeout_refresh),
	(free_busy_template_changed_cb): Watch for a change in the Free/Busy
	template gconf setting, and check for new Free/Busy data if it occurs.
	* gui/e-meeting-time-sel.h: Include variable for notification function
	id on changes to the Free/Busy uri in the EMeetingTimeSelector .
