Web reminder: CVS for ports

[Warren Block]

In one week, CVS for ports will be shut down.  There should be a 
reminder on the main web page.  I've semi-seriously joked with some that 
there should be a floating Javascript countdown timer.  Even a manual 
update that shows the number of days left would be useful, something to 
convey the sense of urgency.

   7 days left: Ports CVS will be shut down on February 28, 2013.  Please
   see http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/ports-using.html
   for alternate methods to update the Ports Collection.
