Base: Improve 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.
