Green 2.13.1

Green is a clean, colorful, fast Python test runner.

If you would like to read about versions 2.9.0 through 2.13.0, which I didn’t make posts about, please see the changelog.

• Tested Green with Django 2.1.5 — it seems to work just fine. Something must have changed between Django 2.0.0 and 2.1.5 that eliminated the problem we were having.
• Properly close the version file after reading it so it doesn’t leave the file handle open for the duration of Green running. Contributed by Nickolas Grigoriadis in #200.
• Drop official support for Python 3.4, though Green will probably continue to work for Python 3.4 for some years before something actually breaks.
• Remove code supporting Python 3.3. We dropped official support in 2015.
• Drop termstyle dependency in favor of using only colorama. Contributed by Ogaday in #199 to resolve #186.
• Show number of processes used in test summary. Contributed in #198 by Ogaday to resolve #85.
• CI fixes/improvements — the world keeps changing.
• Some typo fixes in README.md and help output
