Subject: [PATCH] cloneNode returns this (not Node)

The `cloneNode` return type is incorrect. The type before this change indicated that `cloneNode` returned a `Node`, which then broke any class that extended `Node`. In reality, `cloneNode` will return an instance of whatever the current class type is, a.k.a. `this` (`DocumentFragment#cloneNode` returns a `DocumentFragment`, not a `Node`).
