Resolved issue 396: ExtensibleActionInvoker now uses AutofacDependencyResolver.Current.RequestLifetimeScope to get the current request lifetime scope due to caching introduced in MVC 4. Also removed the property injection of filters from the action invoker, as this is now performed by the filter provider. The injectActionMethodParameters constructor argument was also removed as that is now the only function the action invoker performs.
