Additional cleanups in QuerydslAwareRootResourceInformationHandlerMethodArgumentResolver to make sure a QuerydslRepositoryInvokerAdapter is only applied if the QuerydslPredicateBuilder actually exposes a predicate. Extracted a couple of methods to make sure the mapping pipeline reads nicely.
Previously, when a request was sending an Accept header of some arbitrary *+json, the request was routed through the controllers and might have ended up producing a PersistentEntityResource that was then mapped using an uncustomized Jackson ObjectMapper. That has caused a huge JSON object to be unfolded which is highly undesirable.
We now only answer JSON requests to repository resources that contain an Accept header with any of the explicit JSON media types we got registered.
Tweaked the setup of the ExceptionHandlerExceptionResolver to not expose a bean in the first place but rather use the Spring MVC provided callbacks to register custom ones. We also now make sure MVC is bootstrapped property for integration tests through the inclusion of DelegatingWebMvcConfiguration.
The serializer for projection resources now also invokes ResourceProcessor instances registered for that particular projection.
Original pull request: #238.
Spring 4.3 returns Content-Type headers including the character encoding. We needed to relax our assertions on the content type headers to only check for compatibility.
Deprecated the ResourceProcessor invoking infrastructure in place here in favor of the types moved to Spring HATEOAS. Refactored our codebase to make use of these newly introduced types right away.

Upgraded to JSONPath 1.1.0 as 0.9 is not supported with Spring 4.2 anymore. Tweaked integration tests due to changed semantics and internals of JSONPath >= 1.0.
Extracted store specific tests into separate test modules to prevent classpath overlap between projects. Those tests are now executed in an "it" build profile to prevent the tests being packaged for distribution on release.
Use Map-based repositories and mapping contexts for test in the Core and WebMvc module.
Slightly changed the configuration API for lookup types on RepositoryRestConfiguration.
