default in the header is problematic. E.g. if you use a QScopedPointer inside the \
class you can no longer forward declare it. Thus I never add the = default in the \
header and that's also the reason why I moved one.

implementation as well.
[dpms] Add a Wayland implementation
The Wayland implementation uses the DpmsManager provided by KWayland.
On a timeout it turns the screens off and it supports the trigger
modes. The fade helper is not supported (yet) as it is an X11 only
implementation.</pre>
