Update to our automatic copyright year script

If at some point you used our script to automatically update your copyright year, we wanted to let you know:

We've rewritten that script.

The original script used the Javascript document.write method. Some browsers throw warnings about that method, and Chrome in some cases will block scripts using it outright (we hadn't noticed it blocking this script but we wanted to be safe).

We've rewritten the script so that it now uses a JQuery method that is better supported by browsers.

If you've added this script to your knowledge base previously, we suggest you go take a look at the updated documentation and update your solution accordingly!
