[xmonad] [xmonad-contrib] Patch to add messages IncSpacing/SetSpacing to the Spacing modifier for dynamic adjustment

[adam vogt]

Hi Anton,

Do you actually need the Read/Show instances? I think it's better to
put a function in the message:

data ModifySpacing = ModifySpacing (Int -> Int)

And possibly export these convenience functions:

setSpacing n = sendMessage (ModifySpacing (\_ -> n))
incSpacing n = sendMessage (ModifySpacing (+n))

Regards,
Adam
