The latest patch version of each Django minor version is used.
The build now installs existing pymongo versions.
The build now actually tests against the specified Django version.
Replaced PIL with Pillow.
Added PyPy and Python 3.4 to the build.
Rebase Log:
Installing Pillow instead of PIL for testing since it's recommended and it supports PyPy.
Excluding Django versions that do not work with Python 3.
Improved formatting of .travis.yml.
Specifying Pillow 2.0.0 and above since it's the first version that is supported in Python 3.
PIL should not be installed alongside Pillow.
Also, I installed some libraries that both PIL and Pillow depend on.
It seems I have to be explicit on all envvars in order to exclude Django 1.4 from the build matrix.
The build is now installing pymongo versions that actually exist.
openjpeg has a different name on Ubuntu 12.04.
Restoring libz hack.
Also installing all Pillow requirements just in case.
Fixed the build matrix.
Acting according to @BanzaiMan's advice in travis-ci/travis-ci/#1492.
