Webpack 4 and React 16.6

• We are now on Webpack 4 and React 16.4, plus up-to-date with all our dependencies.
• We removed css-next in favor of postcss-preset-env.
• We removed extract-text-webpack-plugin to mini-css-extract-plugin because of Webpack 4 upgrade.
• Modify webpack config to make sure everything work as expected.

Simplify webpack config to make it easier to reason about

1. Make clear that "publicPath" is a application mount point
2. Introduce "assetPath" for custom location to generate assets
3. Remove unnecessary scripts and make it easier to read
4. Adding auto open browser during dev mode

It contains no breaking changes, all command is still the same, only the underlying wiring is changed.
