[xmonad] Policy on haskell version

Hi Willem,

I think the official policy is to support GHC 6.8 and onwards -- but  
according to the README, xmonad supports GHC all the way back to 6.6.  
I doubt anyone has tried building on such an old GHC in a while, but  
if you want a rule of thumb: the extensions you use should be no more  
than what's supported by 6.6. I'm not sure about the policy for  
xmonad-contrib, but it's probably similar.
