    + changed to form the "revision" number from last
      ChangeLog.txt entry's date/time.
      Revision will now be a 32-bit number, f.e. this
      revision: 1303151640 (YYMMDDhhmm). It will be the
      value returned by __HARBOUR__.
      This can be further formatted for better readability,
      as: '130315.1640'
