	* libebook/e-contact.c (adr_getter): Initialize the address_format
	field. Absence of this was causing crashes.
	(e_contact_set_property): For synthetic attr_type fields, add a
	case for struct/get_set alongside strings. This makes addresses work.
	(e_contact_get_property): For multi_elem strings, count the matching
	attributes instead of trying to get a list from the first attribute
	encountered (which is what list_elem does). This makes e-mail
	addresses work.
