Allow any leaf part to be a message/rfc822 part. (digest_get_uids):

2002-03-11  Jeffrey Stedfast  <fejj@ximian.com>

	* camel-digest-folder.c (camel_digest_folder_new): Allow any leaf
	part to be a message/rfc822 part.
	(digest_get_uids): Recurse the mime structure and add all
	message/rfc822 parts and use a uid scheme similar to IMAP's mime
	part naming convention.
	(digest_get_message): Decode the uid to get the correct mime part.
