Added handing so that on recieving a floor move packet, we rebuild the world according to that packet. When it comes to us hitting stairs, the system just waits for a floor move packet and wont listen to any others or send any. Upon recieving, itll update the floor to the proper one. Added network ready checking so the code can still be tested single player.
Single player doesnt change stairs now. Errors freezing when getting floor move packet.
