Config files for nano course

Several existing configs were copied and modified for the
combination ictce-4.1.13 and Python-2.7.3. The OpenBabel
package contains a Python extension, so they should get a
Python-2.7.X suffix. A Config for molden was added.

I'm not sure about one thing: the OpenBabel package installs a python extension in $PREFIX/lib (without python-2.7.X/site-packages) I hope this is OK. The PYTHONPATH variable is properly set in the module and when the module is loaded, I can indeed import the python extension.
