This requires some code changes:

Because the MonadTrans t class gained a forall m. Monad m => Monad (t m) superclass in transformers-0.6.0.0, the MonadTrans and MonadTransControl instances for ActionT e now have a ScottyError e instance context to match the Monad instance.
Various imports had to be tightened to adapt to mtl-2.3 no longer re-exporting Control.Monad and related modules.

Fixes #283.
