Rewrite WebSocket- and Webserver #62
Description
Rewrite complete webserver and websocket-server structure. Therefore implement websocket-server (socket.io) in every single worker. Doing so, reduces the risk of system crashes (master-process) and synchronization-errors between all worker-processes.
Adding explicit transport-protocol for socket.io to use websockets "disables" default fallback to long-polling that causes many errors and problems.
