Hotfix max layout

Well, yes this introduces again what was done before.

Let me give some time, i am checking whether i can do a better sloppyfocus (or click based).

The idea comes from fvwm, i was a fvwm user before and there is sloppyfocus which is good.

On the attempt made yesterday it showed, that raised windows (i checked for WM_TRANSIENT_FOR and WM_CLIENT_LEADER) actually stayed on top. When the timer got off and you pushed the mouse out of the window then it just put that window into background, which is very good. On fvwm it actually hides after x seconds the window, which also is not the best solution. The effect yesterday was also good, windows stay on top as long the user did not go into the window again and out of it when the timer went away before.

This effect raises the question whether it is possible to achieve similar effect without timer, but by clicking into the parent window, then it should hide the child window.

Also note, that this is only possible by checking for WM_CLIENT_LEADER and WM_TRANSIENT_FOR.
