Three compile-errors in b2c039bbe23af22f8a6eb66d55af7c616583c364

[kfowler]

when trying to cabal build Demos

1) Demos/MFlowPersistent.hs:47:1: Illegal instance declaration for ‘ToBackendKey SqlBackend BlogPost’

• add MultiParamTypeClasses

  2) Demos/MFlowPersistent.hs:48:1: Can't make a derived instance of ‘path-pieces-0.1.5:Web.PathPieces.PathPiece (Key Person)’: ‘path-pieces-0.1.5:Web.PathPieces.PathPiece’ is not a derivable class

• add GeneralizedNewtypeDeriving

  3) Demos/MFlowPersistent.hs:59:25: No instance for (Control.Monad.Logger.MonadLogger IO) arising from a use of ‘createSqlitePool’

• wrap in runNoLoggingT
