New function - even though its broken, we'll assume mailers send latin1

2000-08-31  Not Zed  <NotZed@HelixCode.com>

        * camel-mime-utils.c (append_latin1): New function - even though
        its broken, we'll assume mailers send latin1 headers instead of
        us-ascii.  We just have to encode high chars into utf-8.
        (header_decode_text): Call append_latin1 for appending unencoded
        text segments.
