2004-01-20  Chris Toshok  <toshok@ximian.com>

	* gui/component/addressbook-migrate.c (create_groups): deal with
	the groups/sources already being there.  Essentially make this
	function idempotent.
	(addressbook_migrate): unconditionally call create_groups now.
	move the version logic here from ipl_upgradeFromVersion, and
	include more versions in the set of those we upgrade from.

	* gui/component/addressbook-migrate.h: add major/minor/revision
	args to addressbook_migrate.

	* gui/component/addressbook-component.c (impl_upgradeFromVersion):
	remove the version logic from here.
