New function that replaces handle_multpart() and

2001-10-24  Jeffrey Stedfast  <fejj@ximian.com>

	* e-msg-composer.c (add_attachments_from_multipart): New function
	that replaces handle_multpart() and handle_multipart_alternative()
	for add_message_attachments().
	(e_msg_composer_add_message_attachments): Call
	add_attachments_from_multipart().
	(handle_multipart_alternative): Now only used by
	new_with_message() and is really only designed to work well with
	messages generated by Evolution (ie for editing Drafts and such).
	(handle_multipart): Same.
	(e_msg_composer_new_with_message): No longer calls
	add_message_attachments() because we can't ever have this fail and
	the logic in add_message_attachments() is impossible
	logic. Instead do like what we used to do before the addition of
	add_message_attachments() came along.
