Title: Fixes superfluous change merging triggered by loading remote relationships; initial pluggable value transformer support

Request based on `develop` branch with previous request https://github.com/AFNetworking/AFIncrementalStore/pull/66.

* Fixes an issue where loading remote relationships at least once creates a phantom listener on saves against the ephemeral context used to save information into the requesting context.

* Initial support for value transformers plugged against attribute types implemented as a category on AFHTTPClient.

* Fixes semantics regarding attribute transforming; removes some code and adds some code in `-AFRESTClient attributesForRepresentation:ofEntity:fromResponse:`.
