v3.3.0

Added

• Event LoopErrorOccurredEvent (triggered on request processing exception)
• Listener SendExceptionToStderrListener for direct exception sending (as a string) into stderr
• Listener StopWorkerListener for worker stopping

Changed

• Default package configuration includes LoopErrorOccurredEvent event listeners: SendExceptionToStderrListener and StopWorkerListener #42
• When "debug mode" (app.debug) is not enabled - client will get only Internal server error string instead exception with stacktrace #42

Fixed

• Double response sending on request processing error (calling $psr7_client->respond and $psr7_client->getWorker()->error after that)
