[Bug-gnuzilla] IceCat 31.6.0 release

[Rubén Rodríguez]

GNUzilla is the GNU version of the Mozilla suite, and GNU IceCat is the
GNU version of the Firefox browser. Its main advantage is an ethical
one: it is entirely free software. While the Firefox source code from
the Mozilla project is free software, they distribute and recommend
non-free software as plug-ins and addons. Also their trademark license
restricts distribution in several ways incompatible with freedom 0.
