doc: Socket.prototype.connect(options[, connectListener])

I just copied the relevant options information from net.createConnection and the points about being asynchronous/unneeded from the other defined connect method.

The source code claims that the socket.connect parameters that were already documented is deprecated.

I think that net.connect(options[, connectListener]) should say that it passes the options object to both the Socket constructor and the connect method, and then have all options documented (they currently are not!).
