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.
Summary:
Restrict to process with `X-KDE-DBUS-Restricted-Interfaces=org.kde.kwin.Screenshot` in their corresponding Service file,
to take screenshots.
Such a program can now take immediate screenshots.
Adds a utility file to group KService related logic.
