Convert setup

[lastmjs]

What was wrong?

Related to Issue #962

How was it fixed?

I got rid of the requirements .txt files, updated setup.py, tox.ini, and Dockerfile

If all of my changes work, I believe I'll still need to update some docs.

[lastmjs]

Something simple is wrong in tox.ini, I'm not sure the format based on https://github.com/ethereum/py-evm/blob/master/tox.ini#L45

The circleci error is connected to what is being discussed in #794

You are getting errors because pyethereum depends on rlp<1, and rlp>=1 is being installed. This PR exposes that issue by installing eth-testrpc as part of of the dev extra_requires.

[dylanjw]

Removing this line should fix the failing tests.

[lastmjs]

Removing the installation of eth-testrpc did not work, and I'm not sure now why pytest isn't being installed correctly

[lastmjs]

Everything seems to be working fine now, I'm really not sure what the imports being incorrectly sorted problem is with the linter.

[dylanjw]

Move the dev dependencies back to deps, instead of "extra". The lint tox job needs web3 and its dependencies installed for isort to understand proper import ordering.
