winebuild4
v0.6
- pyinstaller 3.6 is the last one supporting python 2.7 so we're forcing it for 64bit windows builds
- code quality only changes
- remove SSL certificate from winebuild.sh (was causing too many problems, not worth the effort) - set pytools version to 2020.2 in winebuild.sh, as that's the last one to support python2 - fixes #1658
