 In MgMappingUtil::ExecuteFeatureQuery , the call to
 svcFeature->SelectFeatures can throw an MgUnclassifiedException. The try-
 catch was only catching MgFdoException. Thus the exception would not get
 caught, and propagate up into the catch of MgMappingUtil::StylizeLayers,
 which would result in an error log entry.

 The fix is to change it to catch an MgException. Then the
 MgUnclassifiedException is caught. The next call to
 svcFeature->SelectFeatures (using MgFeatureSpatialOperations::Intersects)
 succeeds.

 I also noticed a similar call in MgMappingUtil::ExecuteRasterQuery. We
 should make the same change there as well – to be consistent, and just in
 case an MgUnclassifiedException occurs there too.
