For the Request Builder we need an API for retrieving the class name by specifying the object name in the ObjectManager.
[+FEATURE][+API] FLOW3 (Object): The Object Manager (and the object containers) now provide a method for retrieving the implementation class name by specifying the object name. Resolves #7960
[~TASK] FLOW3 (MVC): The Request object now returns the case sensitive action name, even if it has been set all lowercase by a route. That means that a route http://host/package/mycontroller/myaction will be correctly resolved to myActionAction if \F3\Package\Controller\MyController::myActionAction exists. Addresses #7243
