Recv packets have
	8 bytes of initial header
		29 00 00 00			Magic numbers or so
		XX 00				80 for normal packets 00 for different packet (see normal)
		XX XX				Guess something like latency or such a thing

	(?????? Sometimes the header has size 8 (perhaps even more diff sizes, cmd == 0x0449 || cmd == 0x0307 ====== headerSize += 2)
	6 bytes of packet header
		XX XX				Some kind of type (cmd)
		<extraStuff>		(Not sure what happens with header now, i do know that size is always in the end of the header
		XX XX				Ack number (inc counter)
		XX XX				Size of the packet

		(??????This extra header is sent when the `Size of the packet` is 04???????)
		16 bytes of extra header for multi packets (packets spread over more then one physical packet)
			XX XX			Size of this packet
			00 00			Unknown
			XX XX			Total packets who make up this single packet
			00 00			Unknown
			XX XX			Packet number (starting at zero)
			00 00			Unknown
			XX XX			Total size of the packets (body's only)
			00 00			Unknown

Send packets ack
	85 FF			Type of ACK
	XX XX    		ACK number

	So packets who are not getting ACKed will get a resend from server within X ms
