New function to handle a lot of the filtering/etc that was done in

2002-12-11  Jeffrey Stedfast  <fejj@ximian.com>

	* mail-format.c (mail_format_data_wrapper_write_to_stream): New
	function to handle a lot of the filtering/etc that was done in
	mail_format_get_data_wrapper_text(). This is the first step toward
	getting rid of e-text-to-html crap and using my tohtml stream
	filter instead.
	(mail_format_get_data_wrapper_text): Use the new function.
	(mail_format_raw_message): Use camel streams to write the content
	to gtkhtml rather than using get_data_wrapper_text() and then
	converting that to html and then writing it to the gtkhtml stream.
