DATAREST-34 - Polishing.

Browse Source 
Moved decision logic on whether to return response bodies int RepositoryRestConfig to ease testability of the controller. Added more unit tests and simplified the controller integration tests accordingly. Had to deactivate some Cassandra related tests as they don't seem to handle nulling of properties correctly.

Changed configuration to rely on the presence of the Accept header by default. Deprecated parameterless isReturnBodyFor…(…) methods in favor of the ones taking the Accept header to avoid the null checks on the calling side.

Polished JavaDoc for the isReturnBodyOn(Create|Update) methods. Polished formatting in RepositoryEntityController.

Original pull request: #167.
