Our react components' main.js could not be added in the compression, so sometimes users
would get outdated files served. The LenientManifestStaticFilesStorage now makes sure
that the static files get a hash in the filename. Django compressor was removed since
most of the js and css files are already minified and modern http versions can handle
files better.
Instead of a "create-settings" command, which didn't contain all the options
and was a bit awkward, we now have specific settings used for different things.
