Subject: Improved BitmapCliper. Implemented auto throw when max differences
 reached. Implemented fallback TurboJpeg encoder. Fixed issue with
 UpdateMachine.xml script removing DISPENSERS before IDS_PACKS. Added
 GlobalHost.Configuration.MaxIncomingWebSocketMessageSize for WebSockets
 support for large messages on SignalR.
