kwindowsystem high level functions

[Damian Ivanov]

Yes, I absolutely will, I also have a wrapper that exposes
kwindosystem and kwindowinfo  (and few netwm ones) functions to qml

https://github.com/damianatorrpm/qmlpanel - old revision there,
uploading new one soon)
It is a complete rewrite of my 1st version, I hope to have the 2nd
version complete replacing my 1st one by tomorrow :)
