This is a reimplementation of the old network queue, but using a class. This still uses a separate thread, so that packets can wait if there's any lag. Really, thinking about it, I wonder how necessary this was. On the upside, no singletons this time. Which means that you can have several instances of UDPNetworkManager. That's unintentional, but good to know.
