[xmonad] proposal: add extra screen parameter to runLayout

[Mathias Stearn]

I could see this being useful if you have two monitors with one
rotated to tall mode (looks like a sideways T). It would make sense
for a given workspace to use a different layout if on the tall
monitor. Mayhaps a mirrorIfOnScreen n l layout modifyer.
