Handle repos with missing licenses

[Powersource]

Right now if you call repo.get_license() on a repo that doesn't even have a license file, you get an exception: github.GithubException.UnknownObjectException: 404 {'message': 'Not Found', 'documentation_url': 'https://developer.github.com/v3/licenses/#get-the-contents-of-a-repositorys-license'}.

Personally, I would prefer to just get a None returned instead. Idk what's most pythonic?

The proper way seems to be to return 'NONE'.

Understand your concern, but PyGithub is just wrapper for Github REST v3:
https://developer.github.com/v3/licenses/#get-the-contents-of-a-repositorys-license

If a license is matched, the license key and name returned conforms to the SPDX specification.

When there is no license, Github indeed returns a 404. Guess you will have to catch this exception in your code.
