"Keep above" to make window float

[Mister7F]

First of all, many thanks for this amazing script :) it's by far the best tiling script and made me stay on kde :)

It would be nice if when we click on "keep above" (you can add the button on the title bar in the "windows decoration" settings) the window is floating. Currently this will do nothing as the window is tilled, so it might be a cool option to make a window float :)
