Request: a new release to npm

With #17 switching from the ancient node-sass to sass, it would be nice to have this available on npm release directly.

Until then I can workaround by usiong the git reference to PR #17:

```
        "drupal-js-build": "github:front/drupal-js-build#468f4565916b3a6d086710e646c74d462646a450"
```

Many thanks for the project!
