Fix float behaviour, add shiftWin.

First, if float is called with window which is on a hidden workspace,
then the window will remain on that hidden workspace.

Now the focus should change more as expected:
float w = (view current) . (shiftWin ws w)
    where
        current is the current screen/workspace
        shiftWin ws w is: - view the workspace w is on
            - set focus on w
            - shift ws
            - set focus back to window it was on that workspace
                unless w was focused

shiftWin was add to StackSet.hs
