New class that wraps writing to a GtkHTML stream so that we don't have to

2001-10-22  Jeffrey Stedfast  <fejj@ximian.com>

	* mail-stream-gtkhtml.c (mail_stream_gtkhtml_new): New class that
	wraps writing to a GtkHTML stream so that we don't have to write
	to an intermediate GByteArray.

	* mail-display.c (on_url_requested): Use the new Camel->GtkHTML
	stream - this means we don't have to chew up nearly as much
	memory...yay!
