Update configs and instructions for running tests manually. (#1137)

Browse Source 
- Switch requirements-tests-py3.txt to use mypy GitHub master.
- Exclude .venv{2,3} (suggested in README.md) in .flake8 and .gitignore.
- Update instructions in README.md to be working.
- Remove runtests.sh script and mentions of it -- I can't get it to work
  and the three steps are easily run by hand.
