ref the part. (save_destroy_cb): new function to unref the part when we

2001-10-09  Larry Ewing  <lewing@ximian.com>

	* mail-display.c (save_part): ref the part.
	(save_destroy_cb): new function to unref the part when we have
	closed the dialog.
	(save_url): fake a mime part so that we can save data urls without
	extra effort.  This is less sucky than it seems since it handles
	filenames and ref counting with minimal fuss.
