GAMS: GDXXRW new option CheckDate

GDXXRW is a tool to exchange (read/write) data between GDX files and Excel spreadsheet files. The option CheckDate is helpful to speed up thing when importing data from Excel. If the GDX file is newer than the XLS file it will skip the actual data transfer. As this is COM based this step is somewhat expensive even fro small amounts of data (there is some overhead involved in starting Excel).
