 The current MapGuide implementation does not allow insertion of NULL
 values, using the "MgInsertFeatures"/"MgUpdateFeatures".

 The reason is that the ServerFeatureUtil::MgPropertyToFdoDataValue fails
 to check for null values.

 The attached patch correctly converts properties of type
 MgNullableProperty to the corresponding FDO null values.

 The patch compiles correctly, but I am unsure if all the tested property
 types actually derive from MgNullableProperty (but they should).
