	* mail-offline-handler.c: New file, started by Ettore, finished by
	me, to implement the GNOME_Evolution_Offline interface.

	* Makefile.am (evolution_mail_SOURCES): Add
	mail-offline-handler.[ch]

	* mail-ops.c (mail_store_set_offline): Set a store online or
	offline.

	* mail-send-recv.c (auto_timeout): Don't run auto-check-for-mail
	while the session is offline.

	* component-factory.c (component_fn): Set up offline handler.
