New class to run from Python DDL + DML SQL commands on databases embedded in or connected to Base documents. GetRows() is hardcoded as an exception (cfr. bug #138155) in _PythonDispatcher() - SF_PythonHelper.xba to be able to return 2D arrays to Python. Fix returned empty arrays in the Basic-Python engine: the standard bridge ignores them and returns a null byte sequence instead of an empty tuple.
