Added an identifier-name parameter to the route so that we can configure which route parameter is to be used as id for the entity. This is usefull when nesting routes  eg: /car/1/driver/2
Removed the ServiceManagerAwareInterface from the CrudController because Zend\Mvc\Controller already implements the ServiceLocatorAwareInterface and ServiceLocatorAwareTrait
For readability, I think it is better that keys used in the module.config should be the exact class map. This has the advantage that when you read the code, you immediately can identify which class is invoked by the service locator instead of first having to see in the module.config which class it is referencing.
