Lighttpd: fix ubuntu references in index.html

Lighttpd currently comes directly from Ubuntu and the default index.html file refers to Ubuntu. This is the page you see if you install Lighttpd and browse to localhost:80. I changed the strings to say Trisquel GNU/Linux but it does refer to "upstream bug tracker" for bugs (i.e. ubuntu launchpad) because Trisquel doesn't list any lighttpd bugs.

Add Tox (http://tox.im) packages

Tox is a decentralized distributed (no servers) instant messaging app with built-in encryption, audio/video support, file sharing, group chat and more. So far there has been no way to install the various Tox client applications on ubuntu or Trisquel without compiling from source or using a PPA. Although in development and some features aren't complete, they are already usable and useful.

Order of dependencies:

1

- filteraudio, dependency library of qTox
- libsodium, dependency library of toxcore

2

- toxcore, dependency of all Tox clients below

3

- Toxic (ncurses terminal client)
- uTox  (lightweight GUI client using libx11)
- qTox  (GUI client using Qt)

Fix belenos unity

replace Ubuntu branding. A screenshot is here: https://devel.trisquel.info/akfoss/trisquel-logos-for-unity/tree/master

See merge request !19

This reverts commit bd974458.

I didn't realize there is already a helper make-gnome-colors.
Helpers need to have the source package's name, in this case
gnome-colors-common is a binary package prooduced by source
package gnome-colors.

I'm reverting this, and manually merging the code from both helpers.

8 v2 correct xsane et al snprintf under artistic

xsane, sane-frontends, sane-backends, and sane-backends-extras all use slightly different local snprintf s drawn from an old release of LPRng which are under the Artistic License.  The autoconf setup isn't good enough to detect and use the system snprintf.

The problem was also reported to Fedora and as per spotrh's comment in User Issue 10713 they solved the problem by refactoring the more recent and acceptably licensed snprintf.c from current LPRng. Which they have sent to Sane.  The xsane patch spotrh provided was used to reconstruct this and rather than manage four patches these four essentially identical helper commits copy this over the existing file and update debian/copyright with a shim.  The shim is kept in DATA/blah with the new file for clarity of licensing of the code.

Bugfix ubuntu release upgrader

There were multiple issues:
 - Sed tries to change symbolic links not owned by the user
 - Some packages were removed. This isn't needed when using trisquel chroots, as those packages are never avaliable.
 - The package used one file from ubuntu-drivers-common related to non-free nvidia drivers, that is not needed in trisquel. The source file can be found [here](http://bazaar.launchpad.net/~ubuntu-branches/ubuntu/utopic/ubuntu-drivers-common/utopic-proposed/view/head:/share/obsolete)
