dispatchListener removes connections too early

``` java
public void disconnected (Connection connection) {
removeConnection(connection);
Listener[] listeners = Server.this.listeners;
for (int i = 0, n = listeners.length; i < n; i++)
listeners[i].disconnected(connection);
}
```

shouldn't the connection be removed only after all the listeners were called?
if the connection is removed before, the other listeners may not have the data the need, for example the connection's address.
