This commit updates deprecated webpack plugins, updates old npm packages and fixes #163
Updated css-loader to 3.1.0 for security reasons (as instructed by npm audti).
Replaced extract-text-webpack-plugin (deprecated) with mini-css-extract-plugin.
I added the --mode option to webpack command to clearly distinguish development and production modes.
Removed webpack.optimize.UglifyJsPlugin (deprecated) along with the uglifySettings from webpack.config.prod.js and replaced it with webpack.optimization.minimze.
