This reverts commit 04fb17cb3f.
- Am seeing a bug where only one worker continues processing
on python3.8.
- Ubuntu and freedesktop-sdk are still on 3.7.
- Not using any features of 3.8 yet.
- Also removes color from mypy.
- Used unicode characters to have fractional lengthed bars.

can give the bar's color and background color.
- Changed to python3.6.
- Accepted minor differences in golden files.
- php is now 7.1.
- Updated README.
- Need to test that the AppImage still works.
