* New HWID system prep * Allow HWID to be disabled. Both client and server can now request HWID to be disabled. On the server via CVar, if disabled the client won't send it. On the client via env var, if disabled it won't be sent to the client. This involved moving legacy HWID to be sent in MsgEncryptionResponse instead of MsgLoginStart. This means the legacy HWID won't be available anymore if the connection isn't authenticated. * Fix tests * Fix another test * Review * Thanks Rider
