[vtkusers] Alternate vtkusers archive search

[Jeremy Winston]

Hi Folks,
      I was noodling around, trying to find a way to search the
Insight-Users mailing list archive, and I found that Google's
Advanced Search page with the appropriate fields already filled
in was quite convenient for that purpose.  So I did the same for
vtkusers:

  http://www.google.com/advanced_search?as_epq=pipermail%2Fvtkusers&as_sitesearch=public.kitware.com

Google allows a bit more control over search terms than the
official search page at http://www.kitware.com/search.html.
The trade-off is that you can't specify sort order.
