Add translators of Wiki-imported documentation to authors.txt file

[stephanemagnenat]

The imported documentation from the Wiki should retain the list of authors and translator who contributed to each page. Indeed, while most of the Aseba documentation was written by me, they received some contributions and a lot of translation from others.

Also somewhere the license should be mentioned as being Creative Commons Attribution-ShareAlike 3.0 as stated by the Wiki.

After some thinking I believe the best is to change the copyright notice to mention the Aseba authors and contributors, and put the name of people who translated the documentation in the main authors.txt file under the contributor section, as there are little original contributions to the documentation from people outside the core Aseba contributors.

I changed the copyright information of the documentation in commit 81ca44e to match the one of the main readme file. Most of the documentation has been written by me, and some by others, for example @davidjsherman. Therefore mentioning only me and Mobsya is misleading.

@stephanemagnenat can you handle it ?

I do not have the time. Maybe someone else at Mobsya can help as part of the thymio.org refactoring, as this does not require any programming skills, one must just look at the log and accumulate a list of translators and check for potential contributors to new content.
