Add trove classifier for the Hippocratic License

[thusoy]

Request to add a new Trove classifier for the Hippocratic License.

The name of the classifier you would like to add

• License :: Hippocratic License

Why do you want to add this classifier?

None of the existing licenses prevents use by parties infringing on the declaration of human rights, several projects have started adopting such licenses and it would be nice to be able to browse them programmatically.

Thanks for the request! Currently, adding license classifiers is generally waiting for a resolution to the umbrella issue pypa/pypi-support#142.
