new function, broken out from 'camel_formatter_make_html'.

* camel/camel-formatter.c (write_header_info_to_stream): new function, broken out from 'camel_formatter_make_html'. (write_mimepart_to_stream): same. (find_text_body_part_in_multipart_related): new function. (camel_formatter_make_html): Now tries to deal with multipart/related, multipart/alternate, and text/(plain|html). svn path=/trunk/; revision=1619
