tmp (wokkel): licenses fixes: the licenses headers were wrong, it was fixed: original work from Adrien Cossa is directly under AGPL v3 (with his agreement), work derivated from Wokkel is sublicensed to AGPL v3 as allowed by the original license, to stay consistent with the rest of the code base. Theses files (and only these ones) can be relicensed again to fill Wokkel license if Ralph plan to merge them upstream...
