Fix Django version incompatible for Python 3.3

docs: update python 33 to python 35

find_spec isn't available in Python 3.3; it was added in Python 3.4.

The current required Django version is 1.9.5 which doesn't support
Python 3.3 which causes the Python 3.3 deployment to fail while
using django-ex git repo.

The Django version is modified to use 1.8.x only to include Python
3.3 support.
