Account for a cloned document's base URL

Define a Document's get the base URL algorithm, used by DOM's baseURI getter, to return the document base URL. And have the document base URL take the base URL override into account, which DOM sets when a document is cloned, so that a clone without a base element reports the base URL of the document it was cloned from.
