Advance to Digital Age

The FSF address used in the license boilerplate text is no longer
correct since their offices have relocated. Rather than introduce
the new mailing address which will inevitably change again in the
future, use the website address which is more permanent.

The main COPYING document still has the old address, but I am afraid
to change it because that one doubles as a legal document.
