New function to parse an HTML meta-tag.

2001-07-10  Jeffrey Stedfast  <fejj@ximian.com>

	* camel-mime-utils.c (html_meta_param_list_decode): New function
	to parse an HTML meta-tag.

	* camel-mime-part-utils.c
	(simple_data_wrapper_construct_from_parser): If the Content-Type
	did not contain a charset parameter and it's also a text/html
	part, we have 1 last place to look - in the META html tags. *sigh*

	* camel-mime-message.c (camel_mime_message_get_source):
	s/gint/unsigned since that's what it should be.
