This patch implements overloaded quotation brackets which generalise the desugaring of all quotation forms in terms of a new minimal interface. The main change is that a quotation, for example, [e| 5 |], will now have type `Quote m => m Exp` rather than `Q Exp`. The `Quote` typeclass contains a single method for generating new names which is used when desugaring binding structures. The return type of functions from the `Lift` type class, `lift` and `liftTyped` have been restricted to `forall m . Quote m => m Exp` rather than returning a result in a Q monad. More details about the feature can be read in the GHC proposal. https://github.com/ghc-proposals/ghc-proposals/blob/master/proposals/0246-overloaded-bracket.rst
