proxy timeout does not used here

[MaplerStory]

the timeout in cm_client may be too short ?

typically, connect with the proxy. if the proxy network is not so good, when the client login, it would disconnect and reconnect frequently, at that time the client seems like to be blocked, and no error emit.

maybe, change it like the timeout in TCPConnection https://github.com/DoctorMcKay/node-steam-client/blob/f949d1876cfe230400d1c9d47397cb8c0668dd6f/lib/tcp_connection.js#L58
