Add LICENSE to repo
Up to my knowledge, as one of the authors of the dmx-thymeleaf module, this is a GPLv3 licensed module. The repo does not contain any license information, though.
From my understanding there is no need to change the license of this module from GPLv3 to AGPL-v3.
So, from my point of view I would now add the GPLv3 license to this repo.
There is still an open issue regarding the modules license in #1 (closed)
