more checks about creating new instance of controller on each request - this time if all bindings are static then set them to the initial-devpassed controller and if the total number of lengths are equal with these static dependencies then we ignore the injector and use the initial controller on each request - maximize the performance when simple controller is used - need more cleanup before new release but I hope until Christmas iris developers will be amazed
