Expected copyright line for files edited by Enalean should looks like: `Copyright (c) Enalean, XXXX - Present. All Rights Reserved`.
There are remaining files with the legacy form (`Copyright (c) Enalean, XXXX - YYYY. All Rights Reserved`) and contributors, sometimes (or most of the times in my case), forgot to update it whenever they touch a file. This generates noise in the reviewing process, so we should align every files.
