Support for WKO v3 file format

Summary analysis suggests the new (v29) of the WKO 3.0 file format does
not contain any differences (or noticeable) to the previous version.
This patch enables files to be imported using the existing code instead
of being rejected because they are 'newer than the supported format'.

Further testing and analysis will be performed on the WKO 3.0 file formats
but this patch should enable users of v3 to import there files into GC.
