Release: 2.0.20.52

This release includes:

SPK-10:
- Updated to newer version 20 (from 12 to 20) of List&Label.

SPK-7:
- Addition of exra error-trapping and error-logging to
  prevent/log any problems for SparkEngine.

REMARK:
Updating froma 12 to 20 version cannot be done by only replacing the exe-files!
Instead of that please install a complete new version via the Spark-setup-procedure.
Be sure to make a backup of the existing SPARK.INI-file before you do that, so 
you can use that in the new version.
