DSPDevice*Engine: Add signals to indicate when commands have been processed. DSPDeviceSourceEngine: Fix small memory leak. DSPEngine::removeDeviceEngineAt: Remove wait to avoid blocking thread. Return QThread to get finished signal. DSPEngine::addDevice*Engine: Don't call deleteLater for device*Engine, as these objects are deleted manually in MainWindow, which will crash if deleteLater called first.
