Clipboard package: Unicode update

Hi all, Clipboard is a package for interacting with the (Windows only, currently) system [1]. Recently, I have received a patch that, to avoid problems with unicode characters, saves the content in the clipboard in Unicode format (instead of normal text). I thought that this is a change in the behaviour of the function (though the interface remains equal), so I'm hesitating if I must add this feature in a new function or to modify the current declaration. I await your opinions. Daniel Díaz, Clipboard maintainer. -- References [1] http://hackage.haskell.org/package/Clipboard
