-C -> S : Connects
-C -> S : Sends handshake
-S -> C : Sends handshake response
-C -> S : After authenticating (if needed), sends the login packet
-S -> C : Either kicks (invalid login) or sends a login response
-S -> C : Sends pre-chunks and chunks and entities
-S -> C : Sends spawn position
-S -> C : Sends inventory [Need to verify this since inventory changed] (beta 1.1_02: looks like Window items with type=0, then a Set slot with window id = -1 and slot = -1)
-S -> C : Tell the client they're ready to spawn by sending a position + look packet. Note: The stance and Y should be swapped when the server sends it to the client
-C -> S : Sends a position + look packet to confirm the spawn position, with the stance and Y swapped back to the correct positions
