Since we also license under GPL-3.0 WITH Qt-GPL-exception-1.0,
this applies only to a hypothetical newer version of GPL, that doesn't
exist yet. If such a version emerges, we can still decide to relicense...
While at it, replace (deprecated) GPL-3.0 with more explicit GPL-3.0-only
Change was done by running
find . -type f -exec perl -pi -e "s/LicenseRef-Qt-Commercial OR GPL-3.0\+ OR GPL-3.0 WITH Qt-GPL-exception-1.0/LicenseRef-Qt-Commercial OR GPL-3.0-only WITH Qt-GPL-exception-1.0/g" {} \;
