Reference to freecode.org in the handbook

[Steven Santy]

Hello.  "freecode.org" is mentioned in  the _FreeBSD Handbook_ on page:

https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/ports-finding-applications.html
 .

According to http://www.freecode.com/about :

"The Freecode site has been moved to a static state effective June 18, 2014
due to low traffic levels and so that folks will focus on more useful
endeavors than site upkeep."

Thank you for your ongoing commitment to both a high-quality OS and its
documentation.

-Steve
