Build multiplayer capabilities

This is a big one. There's a lot of work and discussion to be had with this issue, but Nitro should facilitate easy multiplayer communication. There's all kinds of methods and models that could be used for game synchronization and given that Nitro is a general purpose engine we should seek to allow users to pick a "weapon of choice" for multiplayer synchronization as each model provides different benefits for different games.

Nitro is first and foremost an engine designed for the people using it. Right now I am the only user of it, so I'm going to limit the scope of this issue to the synchronization model needed for the game I am making. I haven't decided what that model is yet but as soon as I know I'll put it here.
