[evolution/webkit: 59/113] Add EM_FORMAT_HANDLER_COMPOUND_TYPE flag to EMFormatHandler



commit ab26e73c687153f9d3e1ba518761a4e5f0eb3d82

    Add EM_FORMAT_HANDLER_COMPOUND_TYPE flag to EMFormatHandler
    
    This flag says, that the particular mime type is compound
    (application/mbox, message/rfc822) and that we should attempt
    to parse it even though it's an attachment
