The main advantage of SPDX license identifiers over the traditional license headers is that it's more difficult to overlook inappropriate licenses for kwin, for example GPL 3. We also don't have to copy a lot of boilerplate text. In order to create this change, I ran licensedigger -r -c from the toplevel source directory.
