Author: Dan Williams <dcbw redhat com>

    Make camel_mime_message_dump() dump message contents
    
    Previously unimplemented.  Dumps in hex and ASCII:
    
    class: CamelMimeMessage
    mime-type: text/plain; charset="UTF-8"
    content class: CamelDataWrapper
    content mime-type: text/plain; charset="UTF-8"
    content len 967
