1. Added Context.hideFromContextListeners() which makes invisible for listeners.

2. Made sure that ContextListener.contextCreated is called only once. After a resent change to call the method from Context.enter, not from Context constructor the method would be called each time on first enter which broke the debugger.

3. Using new listener utilities from Kit instead of ListenerArray methods that would create a special storage object only if there is more then one listener.
