  Changed paths:
    M src/Products/PythonScripts/PythonScript.py
    M src/Products/PythonScripts/tests/testPythonScript.py

  Log Message:
  -----------
  Show proper error message for not allowed identifiers.

Due to interaction between Python(Scripts) and RestrictedPython,
following identifiers are not allowed:
- context
- container
- script
- traverse_subpath

Instead of throwing an "IndexError", now a proper error messsage
is shown.
