Update frontend code

Introduce webpack to bundle required dependencies instead of relying on global libraries. Those global libraries are deprecated and will be removed soon.

I tried to change the existing code as little as possible. However, the diff is huge because I fixed the indentation (tabs and spaces were mixed). Additionally, I tried to keep package.json and webpack.common.js as minimal as possible and took some inspiration from other official nextcloud apps.

Npm scripts:
- Production build: `npm run build`
- Development build: `npm run dev`
- Build and watch for changes: `npm run watch`

The build script should be run before pushing a release. The source files (inside src/), installed packages (inside node_modules/) and various js configs (webpack.*.js, package*.json and babel.config.json) can be omitted from a release. Webpack will output the generated code to js/.
