Why does URI.fragmentQuery not return URI

Hi,

would it be possible for [URI.fragmentQuery](https://github.com/medialize/URI.js/blob/master/src/URI.fragmentQuery.js#L102) to return `URI` instead of a `{}`?

That way one could `require(['URI.fragmentQuery'], function(URI) {})` instead of having to require both `URI` and `URI.fragmentQuery`.
