	** Fix for bug #487922
	(Sometimes evolution does not recognize attachments)

	* prefer-plain.c: (export_as_attachments): New helper function to
	export message parts as attachments. This will traverse whole
	hierarchy of message's parts in multipart message.
	* prefer-plain.c: (org_gnome_prefer_plain_multipart_alternative):
	Use this function to export other parts as attachments.
