EventEmitter leak

[jkp]

There seems to be an EventEmitter leak in the client code. If an error is thrown when logging in for example, things don't get cleaned up correctly.

I could be wrong but I don't see any calls to removeListener that balance the on calls that are made so this is probably the problem.

There is also a problem where the socket can be left open in the event of a bad login. Steps to reproduce: call connect() with bad credentials, then you will be left in a state where the runloop fails to exit (the only way to fix it is to close the socket on the client manually - client._socket.close())
