Description

I would like to add more event listeners to the SSHD - e.g., ScpEventListener, SftpEventListener, TcpIpForwardingEventListener - in a similar manner that SessionListener is used. In order to facilitate this I have made the following changes:

• SessionListener extends EventListener - which is the Java "standard" marker for such interfaces
• Added a proxy wrapper around such listeners in order to avoid the ```for (Listener l : listeners) { l.signalSomeEvent(...) }

  ``` pattern again and again.
