Introduces the XML::Document type to wrap a Pointer(LibXML::Doc), while XLM::Node is meant to wrap the subtree Pointer(LibXML::Node). The XML::Document inherits from XML::Node and acts exactly like a XML::Node, so it should hopefully be a transparent change. The main advantage is that we now register a single finalizer instead of one for every node (only the document needed a finalizer). Sadly, it doesn't allow to have a dual strong reference from a document to its nodes, and from the nodes to their document. Boehm GC still complains about cyclic finalization, despite only the document having a finalizer.
