adjust to build with monad-control-0.3

I had to, I hope temporarily, lose my nice Annex newtype, and use a type
synonym. This because I cannot find a way to derive a MonadBaseControl
instance of the Annex newtype. I've emailed Bas van Dijk in hope he can
help get the newtype back.

Otherwise appears to build & work.
