Detect text/html parts that were marked as text/plain and re-tag them as

2002-12-16  Jeffrey Stedfast  <fejj@ximian.com>

	* camel-mime-part-utils.c
	(simple_data_wrapper_construct_from_parser): Detect text/html
	parts that were marked as text/plain and re-tag them as text/html
	parts. Note: currently just checks if the first non-lwsp char is a
	'<' - but we might need to be smarter about this? *sigh* Stupid
	Windows mailers.
