IceCat 31.5.0 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.

The main improvement in this version is the support for Windows, MacOS
and Android, which added to GNU/Linux cover most user platforms. All
versions are cross-compiled from GNU/Linux, so only free software is
used for building. The published binaries have been tested for:

 * Windows Vista or newer
 * MacOS 10.4 or newer
 * Android 2.3 or newer
 * GNU/Linux with glibc 2.15 or newer (Debian Testing, Ubuntu Precise)
   Binaries for Trisquel, Parabola and Fedora will be provided by the
   distros as usual.

Thanks to the developers of TorBrowser, on which the multiplatform
support was based!
