Complete the test matrix for all supported Python/Django versions

Tox and Travis CI now test all supported versions of Python and Django.

Tox no longer fails if Django master fails. As master is always in flux,
it is guaranteed to pass.

Document all of these supported version as trove classifiers. Allows
library consumers to easily scan for available support.
