MsgLoginChallengeS

The account server sends this message to client to start the SRP6 challenge. The challenge consists of the calculated public ephemeral value (B = kv + g^b mod |N|) and the player's salt (S). The client expects this message in response to MsgAccountSRP6 / MsgAccountSRP6Ex, and responds with MsgLoginProofC.
