Update to 2.23:

13/11/2005  *** v2.23 ***

            - Uses DatLib v2.11.
            - Added support for 'board', 'colordeep', 'credits' and 'archive'
              (fully supported by ListInfo, ListXML and Delimited formats).
            - M1 XML loader now retains the 'board' information (see above).
            - M1 XML will not use hex for ROM sizes after all... changed back!
            - Improved the way that the Nebula driver handles Neo-Geo ROMs.
            - Fixed Nebula Jukebox driver for Neo-Geo ROMs (broken in v2.7).
