ports count milestone according to FreshPorts

[Mark Linimon]

According to http://www.freshports.org/ we have crossed the 23,000 port
barrier (currently 23,031).  If I read this correctly the commit that
put us over the top was the addition of devel/py-Products.CMFActionIcons.

I appreciate all the hard work folks put into the Ports Collection.  Now
I'll go back to trying to make sure we have a way to build them all :-)
