Publish as Package on PyPI to ease installation

[johannesjh]

• Read the Python packaging guide: https://packaging.python.org/tutorials/packaging-projects/#uploading-your-project-to-pypi
• Setup Makefile targets similar to fava, using twine
• Write a CHANGES file
• Set the initial version to 0.1.0 in smart_importer/__init__.py
• Tag v0.1.0 in git
• Create a release v0.1.0 in github
• Publish using twine on test.pypi.org and verify that it worked
• Publish using twine on production pypi.org
• Bump the version to 0.1.1-dev in smart_importer/__init__.py

With setuptools_scm (#84), there's no need to bump versions and such, tagging is enough. I'll make a first release today.

[yagebu]

Done.

@johannesjh Let me know if I should add you as a maintainer on PyPI

[johannesjh]

Hi, thank you for publishing the package. And thank you for cleaning up the setup configuration, setuptools_scm looks very nice. If you could add me (account name: johannesjh) on pypi, that would be great, thank you.

When I install smart_importer = "*" with pipenv, I get numpy incompatibility errors.

ValueError: numpy.ufunc size changed, may indicate binary incompatibility. Expected 216 from C header, got 192 from PyObject

This happens at runtime with import smart_importer. I am sandboxed with no numpy outside of my pipenv's virtualenv.
