package.json: peerDependency no longer works

While performing an `npm install` the following message appears:

> $ npm install
> npm WARN peerDependencies The peer dependency cldr-data included from globalize will no
> npm WARN peerDependencies longer be automatically installed to fulfill the peerDependency
> npm WARN peerDependencies in npm 3+. Your application will need to depend on it explicitly.
>
> > cldr-data@28.0.2 install D:\Repos\globalize\node_modules\cldr-data
> > node install.js
>
> Warning: Skipping to download CLDR data, because `cldr-data` is a peer dependency. If you want it to be downloaded, make sure it's listed under `dependencies` or `devDependencies` of the `package.json`of your application.
