Added Py3.{5,6} & Django 1.11. Removed Py2.6 & Django <1.8 (#9)

* Quick fix for the DJANGO_VERSION error when using Python >= 3.6 (version calculation caching removed because it is not a performance penalty, urls are lazy and are calculated only once per an app start).

* Added Py3.{5,6} & Django 1.11. Removed Py2.6 & Django <1.8

The latest Django LTS is 1.11. Its ok to support up to the "LTS -1" (1.8) only.
The next Django LTS is 2.0, and will be Py3k only, so lets start testing with Py3k!

* Mark as Py3k compat on setup.py
