Rearrange the save filter stuff so that we save raw streams for all mime

2002-02-28  Jeffrey Stedfast  <fejj@ximian.com>

	* camel-mime-part-utils.c
	(camel_mime_part_construct_content_from_parser): Rearrange the
	save filter stuff so that we save raw streams for all mime
	parts. If the mime part turns out to be a multupart, then don't
	bother saving the raw stream, we only need to save the raw stream
	for leaf parts.
