Update Django and Python versions in Travis config (un33k#31)

* Add Python 3.6 and 3.7-dev to the testing matrix. Remove Python 3.3. Add support for Django 2.x.

* Add Python 3.6 to setup classifiers.

* Use range for Django 2.0 (pypy on Travis can't find Django 2.0.1).

* Add pypy3 to Python versions and disable Django 2.0 testing on pypy.

* style: remove unused import
