In xml responses, if the result is an empty array we want the response to look like this: <posts type="array"/> not like this (the default): <nil-classes type="array"/> This refactors controllers so that this is done automatically instead of having to manually call `@things.to_xml(root: "things")` everywhere. We do this by overriding the behavior of `respond_with` in `ApplicationResponder` to set the `root` option by default in xml responses.
