The signaling server protocol has been rewritten to use JSON format to be more readable. Lobbies now support both mesh and client/server modes (selected during creation). The client/server mode uses the SceneMultiplayer relay mode as implemented in beta4. The demo now uses an RPC for pinging, and connects to the MultiplayerAPI instead of using the raw MultiplayerPeer.
