Server listens correctly with threads and stdin reader thread.
Client does nothing currently gutting UDP_Write for a UDPbase class
introduced in this commit.
< Bubblegumdrop> SDLNet_UDP_Open seems to call SDLNet_Read16 (which is just SDL_SwapBE16)
< Bubblegumdrop> But on the server side I don't use SDLNet_UDP_Open to host the port
< whitt> probably the sender was flipping it but the receiver wasn't and so they were incompatible
< Bubblegumdrop> removing the SDL_SwapBE16 on the client side fixed it
