Added more TransferableGraphs.writeTransferableGraph methods

* writeTransferableGraph(RequestProcessor,
                         TransferableGraphSource,
                         File,
                         TGStatusMonitor)
  writes the specified TG source into the specified file as a variant
  (i.e. datatype + data)
* writeTransferableGraphVariant(RequestProcessor,
                                TransferableGraphSource,
                                RandomAccessBinary,
                                TGStatusMonitor)
  writes the specified TG source into the specified output binary file
  as a variant (i.e. datatype + data)
