We need to include the {google:contextualSearchUrl} here too.  I know we're not
really using this for anything now, but I think we will be able to use it very
soon and it will be very helpful.

Also it looks like the contextualSearchVersion is not listed on this line.  I
think we probably want it here too, but not sure.

Done. The version was primarily for indicating a /search is a contextual search
request, but it's possible we might actually want it for versioning too, so
including it here makes sense.
