Added nested class 'XConfig.__NODE__' - this subclasses an IXMLDOMNode object to a custom object for better and easier manipulation. The method '__Sel' is similiar to 'selectSingleNode' but instead of returning an IXMLDOMNode object it returns an 'XConfig.__NODE__' object. Internal property '__doc' is renamed to '__dom' to allow 'XConfig.__NODE__' objects to __Call/__Get/__Set 'XConfig' (dynamic) methods and/or properties.
