This is deprecated API and will be dropped at some point, in favor
of projects shipping their own CSS.
Follow https://github.com/cockpit-project/starter-kit/blob/master/webpack.config.js
approach on how to use PF CSS.
Also:
* Replace extract-text-webpack-plugin with mini-css-webpack-plugin as
the former is deprecated: https://webpack.js.org/plugins/extract-text-webpack-plugin/#usage
* Upgrade PF module dependency
* Reduce the css files that are linked through webpack. Instead include
from the JS the CSS files and let mini-css-extract-plugin do the rest of
the work
eslint is much more powerful and flexible than jshint, and we don't want
to promote writing new projects with pre-ES6 code.
As a side effect, this also avoids downloading PhantomJS (see
https://github.com/jshint/jshint/issues/3318), thereby cutting down
node_modules/ from 470 MB to 210 MB.
Rename some files and change some identifiers to be neutral to the
application name. This makes it simpler to change everything to a proper
name when cloning this project.
Document in the README how to find the remaining places to change.
