Update .travis.yml for new dependencies
Review Request #7580 — Created Aug. 11, 2015 and submitted — Latest diff uploaded
Since we now allow Django 1.7 and 1.8 on master, we have to make sure
to install the correct Django version before runningsetup.py develop
or it will always install the latest version (which is incompatible on
Python 2.6).
