Additional parameters for Bing geocode method

Parameters to influence the form of the response such as 'culture', 'includeNeighborhood' and 'include' added as optional parameters to the request.
I see `queryParse` as also accepted, per Bing docs: http://msdn.microsoft.com/en-us/library/ff701711.aspx. So how about `include_country_code` or something else more specific as the parameter?
