Formatting and the new version of the youtube-api package

Minor edit in README file, formatted the dependencies in `package.json`.

Also, another version of [`youtube-api`](https://github.com/IonicaBizau/youtube-api) is available. Check the [changelog](https://github.com/IonicaBizau/youtube-api#v022).

I am preparing the support for `POST`, `PUT` and `DELETE` request methods.
