Modernize project structure

[pipermerriam]

This project was made without the use of our standard project template.

https://github.com/carver/ethereum-python-project-template

The following should be cleaned up to closer match our modern project structure.

• remove requirements-dev.txt in favor of using extras_require pattern.
• add classifiers to setup.py
• update the readme to contain the appropriate badgest, title and general structure.
• update the tox.ini flake8 environment to use the more modern lint name as well as the same approach, installing from extras_require.
• add python_requires (and exclude python==3.5.2)

Extra credit for finding other tangible differences and fixing them.
