    Fix loading size of attachment (bug #667541)
    
    I think I found a simple way how to get size of an attachment: just looking
    on size of the respective MIME part (and multiplying it by 0.73 if it's base64 encoded).
    This seems to be more simple and faster then the previous method, which didn't
    work for the webkit port since camel_folder_summary_guess_content_info always
    returned NULL
