Remove dependencies from package.json

Client site libraries that are published on NPM usually don't
specify any dependencies field so the user can decide for
themselves on how to load the dependencies (though a CDN for example).

Other examples of client side libraries that have been publisher to NPM
and have no dependencies specified:
https://github.com/angular-ui/bootstrap/blob/d9dd5803aef1411e13a70bbde3f8074abd3373e5/package.json#L6
https://github.com/rubenv/angular-gettext/blob/31a175c4d85e793a694bc5dfeb956fccabd05d76/package.json#L25
https://github.com/angular-ui/ui-router/blob/696148f199002adbdfcf864894acf96894e06ed6/package.json#L56

The definitely don't have their devDependencies in their normal
dependencies as this library does with grunt.
