Fix

The old method of releasing to pypi broke for whatever reason and switching to a supported toolchain is easier than debugging the old one.

Additionally:

- Update gitchangelog
- Fix license entry
- Set long description type
- Gitignore the temporary readme file

-------------------
- Add support for python 3.7 and 3.8 in package classifiers. [Albert
Wang]
- Remove support for python 2.7 in package classifiers. [Albert Wang]
- Remove python 2 specific import logic. [Albert Wang]
- Remove python 2 specific logic. [Albert Wang]
- Add ability to skip archived repositories. [Gary Moon]

-------------------
- Add flake8 instructions to readme. [Albert Wang]
- Fix regex string. [Albert Wang]
- Fix whitespace issues. [Albert Wang]
- Do not use bare excepts. [Albert Wang]
- Add .circleci/config.yml. [Albert Wang]
- Include --private flag in example. [wouter bolsterlee]

By default, private repositories are not included. This is surprising.
It took me a while to figure this out, and making that clear in the
example can help others to be aware of that.

-------------------
