Scud Race Online drop in/drop out test

I still need to implement a UI, this is purely a demonstration of how it works and will be much more user friendly upon release. In previous releases, I have used a coturn node for NAT traversal and linking players to play online. While it "worked" we were still somewhat limited by emulation. Scud Race Online uses dedicated servers for online racing now. When a player registers a session they can either wait for opponents in a lobby or start the game and get playing. When another player joined the game server, they are placed in a queue to join the session and filtered in once the race is over. If a player drops out during a race there car goes to the side of the road as if AFK and then remaining players are resynced at the end of a race. No more having the lobby collapse cause a machine didn't start in time or left the game.
