Added
- Github workflows for Actions.
These are just starting but they may replace Travis CI in the future.
- Made 3.8 the default version for CI testing.
Fixed
- Added needed `install_requires` entries in setup.py to allow Statick to work out of the box (in the pip sense).
- The `statick_ws` command now supports running without an output directory.
- The xmllint unit tests will be skipped if xmllint executable is not available.
This can happen when apt dependencies are not going to be installed.
Removed
- Python 3.5 is no longer supported.
It is not getting updates any longer, and is not available on Github Actions.
