patch for databases/pxtools, BLOBs in pxtools-0.0.20

[Kurt Jaeger]

Hi!

I've had a paradox database to convert and found some issue with BLOBs:

If a file defines BLOBs, but the BLOBs do not contain data,
the PXBLOBtoBinary does not correctly defines s and s_size and
then binary_to_sql() fails.

It can be fixed with the following patch.

Hope this helps.
