Fix licencing situation
Gwenview is mostly licenced under GPL 2.0 or later. Some contributors in the last month (including me) were using LGPL licences that are more restrictive about the specific version. This commit changes licences with approval of the copyright holder so that the licencing situation is kept the same way as it was orignally intended by prior maintainers.
