LICENSE missing in pypi sdist

It's usually best practice to include the LICENSE file in any source code tarball.

Some Linux distributions (are required to) include them when packaging, others (such as Arch Linux) might have a package with default licenses, which is then referred to.

For maximum compatibility, it would be very awesome, if you could include the LICENSE in the sdist! Thanks!

@Qirky thanks for the short turnaround! :)

Hm, but it seems the LICENSE is still not included in the sdist of 0.7.34

It's been added to the setup.py file so I have no idea why it isn't being uploaded. The License version number is on the PyPI page (cc-by-sa-4.0) but the file isn't included...

I believe this PR should be sufficient to get the LICENSE file into the source dist #220
