Re-implemented to use streams. Also no need to check for html since

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

	* mail-format.c (handle_text_plain): Re-implemented to use
	streams. Also no need to check for html since
	camel-mime-part-utils.c now does this for us and will re-tag the
	mime-type as text/html thus the UI can be completely ignorant of
	this process.
	(handle_text_plain_flowed): Removed.
	(write_one_text_plain_chunk): Removed.
	(try_uudecoding): Removed.
	(try_inline_binhex): Removed.
	(handle_text_enriched): Re-implemented to use streams too.

2002-12-15  Jeffrey Stedfast  <fejj@ximian.com>

	* mail-format.c (write_text_header): Change the order of the args
	to be consistant with other write functions.
	(write_date): Same.
	(write_field_row_begin): Here too.
	(write_headers): Here too.
	(write_one_text_plain_chunk): Don't strdup just to pass it to
	mail_text_write() so that it can dup it yet again into html text
	and dup it yet a 3rd time into a GByteArray. Instead just write it
	to gtkhtml.
	(handle_*): Fixed arguments to take a MailDisplayStream instead of
	a GtkHTML widget and a GtkHMLStream.

	* mail-display.c (mail_display_render): Create a MailDisplayStream
	to pass to mail_format_mime_message() and
	mail_format_raw_message().

	* mail-display-stream.[c,h]: New stream to replace
	mail-stream-gtkhtml.c

	* mail-stream-gtkhtml.[c,h]: Removed.
