  * 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
