Port fix of Ticket #1298 to adsk branch

[Problem]:
Create a join and a calculation due to the SDF/SHP data source. Preview the new class in the MapGuide Studio, and view data. There is a FDO exception: ?\226?\128?\156An exception occurred in FDO component. Item '' not found  in collection?\226?\128?\157.

[Reason]:
In MG Server, in the MgOpSelectFeatures::Execute()method, we get the className from WebTier. And the className should be qualified, formatted like schemaName:className(e.g. Default:Class1).
Then we parse the qualified schemaName by invoke the function MgUtil::ParseQualifiedClassName(CREFSTRING qualifiedClassName, REFSTRING parsedSchemaName, REFSTRING parsedClassName). If the schemaName is not qualified, the parsedSchemeName will be empty.
At last use the parsedSchemaName  to get schema from the SchemaCollection like this: FdoPtr<FdoFeatureSchema> schema = (FdoFeatureSchema *)schemas->GetItem(parsedSchemaName.c_str());
If the parsedSchemeName is empty, the GetItem method will throw a FDO exception as above.

The problem is, in the WebTier( in showclass.php), we are using  a unqualified className to select features like this: $featureReader = $featureSrvc->SelectFeatures($resId, $className, null);
Then the exception is thrown from the  MG Server.

[Solution]:
In the showclass.php, we should use the qualified className to select features.
$qualifiedClassName = $schemaName . ":" . $className;
$featureReader = $featureSrvc->SelectFeatures($resId, $qualifiedClassName, null);
