Upload non-wheel format to pypi

[Matt Robenolt]

Right now, only .whl files are being uploaded, which breaks for a version of pip that doesn't support wheels. Should upload the .tar.gz version as well as a result of setup.py sdist.

Any chance we can get this issue resolved, can't deploy at the moment

I've just uploaded the sdist for 0.7.1.
