Should be able to specify Transcoder to use when querying a view

All of the other methods in the interface support providing a Transcoder on each call and not necessarily relying on the default Transcoder configured in the connection builder. However, there is no way to do this when querying a view. This really only becomes an issue in combination with the "include documents" feature. When you're working with a document that has been Transcoded it will fail when you call getDocument() on the results unless you register a default Transcoder. It would be more consistent if we could pass a Transcoder to the getDocument() call (or configure it for the Query object)... and it would be even nicer if we could benefit from the duck typing logic to get the document as a JSON String if it's been identified by Couchbase as json.
