make-compton: Added grafical way of enabling and disabling compton.

I've made a script that allows the activation and deactivation of Compton's effects through systems settings.

Some modifications have been made like the fact that some scripts have been moved to separate files to avoid writing "\" before some special characters and to "clean" the helper up.

Zenity is being used to ask the user what to do so "zenity" have been added in the "dependencies" section of the package.

I hope everything is correct now.

Use unity-control-panel when avaliable

indicator-datetime package uses com.canonical.indicator.datetime gsettings namespace, and that namespace is managed by unity-control-panel, not by gnome-control-panel.

Fixes #12087 #13233 #13379

disable abrowser middleclick on content

Avoids loading pages from clipboard when middle-clicking on a page.

This prevents loading pages by mistake, as that can be a privacy issue.

Doxygen: fix proprietary browser references

Doxygen generates API reference documentation from special comments extracted from source files.

It supports generation of graphs using 'dot', part of GraphViz. These graphs can be generated as SVG files, but not all browsers suport SVG. So if SVG isn't supported, a list of suggested browsers is displayed to the user browsing the generated webpages. By default the list contains proprietary browsers.

This patch changes that list to suggest only freedom respecting browsers (which support SVG rendering).

I also filed this issue to the gnu-linux-libre mailing list, but got no feedback so far. I decided not to wait and fix this issue here in Trisquel.

Add new helper for Debian testing package.

Belenos

I've encountered a problem when I tried to create a configuration file on my home directory. When I tried to execute the "compton-launcher" it didn't launch compton but the following message appeared:

parse_config(): Failed to read configuration file "~/.config/compton.conf

Replacing "~" with the environment variable "HOME" solved the problem.

Remove z88dk nonfree files

See http://www.z88dk.org/forum/viewtopic.php?pid=8504. The package z88dk was blacklisted, but the files with noncommercial restrictions are not required (test suite and keyboard driver), so I made a package helper to remove those files. Requires trisquel/ubuntu-purge!11.

README -> README.md

Since these repositories are hosted on `gitlab` I thought it was nice to have the `README` in markdown format.

Add make-tcltrf helper

This helper replaces the nonfree code for the RIPEMD hashing algorithm with free code that I wrote and was included in Debian: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=751879.

Fix copyright file for grace

The copyright file of grace was taken from labplot, a completely different package. The only thing in common is the cephes library. I replaced the copyright file with the correct one from the Debian grace package.
