Robotlegs utility LazyMediator for better performance in games.

How to use

• Override the mediatorMap getter method in context to:

 return _mediatorMap || (_mediatorMap = new LazyMediatorMap(contextView, injector));

• In the constructor of view classes add:

 new LazyMediatorActivator(this);

Why it

• LazyMediatorMap don’t listen events of display list and check every added/removed view.

How it works

• LazyMediatorActivator dispatchs LazyMediatorEvent when the view is added/removed from stage.
• LazyMediatorMap listen to the LazyMediatorEvent from contextView then check the view.

Current version is compatible with Robotlegs v1.4.0+ because _active field (used in LazyMediatorMap) was removed there.
