License mismatch

[hc-sven]

The LICENSE file lists LGPL-2.1 as the license but the composer.json lists it as LGPL-3.0. Which one is it? Generating a list with metasyntactical/composer-plugin-license-check uses the composer.json file an thus outputs 3.0 as the license.

I'll need to think it through but the license version was added to the composerjson after the LICENSE file was added. I'm not sure if that was an intentional change, but the license indicated in the file headers is still 2.1 so I'm inclined to go with that version for now.
