Add the new websocket package (which is just a helper for kataras/neffos) and an example for go server, client, browser client and nodejs client. Add a .fossa.yml and the generated NOTICE file for 3rd-party libs. Update go.mod, go.sum. Update the vendor folder for pongo2 to its latest master as well

```sh
$ npm install --only=dev # install browserify from the devDependencies.
$ npm run-script build # browserify and minify the `app.js` into `bundle.js`.
$ cd ../ && go run server.go # start the neffos server.
```

> make sure that you have [golang](https://golang.org/dl) installed to run and edit the neffos (server-side).

That's all, now navigate to <http://localhost:8080/browserify>.
