Split MonaIO class from mtl

I propose that the MonadIO class be split from the mtl package.

The class would live in a new package, titled monad-io, in a new module titled Control.Monad.IO. This class would then be re-exported by Control.Monad.Trans. This would add a dependency on the new package to mtl.

This would result in no change to the use or haddocks of mtl.

A package implementing the new package half of this proposal may be found at http://community.haskell.org/~aslatter/code/mond-io
