Multiplayer

This might not fit into one issue, but here's roughly what we need to get multiplayer working:

• Handle "other person's gamestate" messages from the server
• Interpolate other person's gamestate with local physics
• Make sure input etc. is only handled for our window
• Display "opponent" somewhere visible on the other screen
• Handle matchmaking on the server
• Play audio when the opponent has a collision

To make multiplayer work on the server, the way game sessions are handled will have to change dramatically. Here's a rough synopsis of the changes that need to be made on server-multiplayer:

• Spawn a new thread for each concurrent connection
• Initial negotiation for either an AI player or an opponent
• If AI requested, start AI thread etc. (more details to come)
• If human opponent requested, check if there's anyone waiting:
  • If there is, match with them
  • If not, add ourselves to the queue
