Base: Imporove Python exception handling

If the Python profiler is activated then transporting the dict as exception object is broken where InteractiveInterpreter::runCode() fails to restore it.
To fix the problem use Exception::setPyException() instead inside the macto PY_CATCH and the generated wrapper code.

This also improves exception handling in command line mode.
