HTTP Bind session listeners are never invoked
SessionListener instances can be registered with a HttpSession. However, these instances are never invoked.
The API for the listeners that aren't invoked are now removed.
I'm removing support, as this has apparently never worked.
Note that it continues to be possible to register SesionListener instances that trigger on events for all (as opposed to a single) HttpSession instances through org.jivesoftware.openfire.http.SessionEventDispatcher
