Detach Events

[azmartone]

We need a way to remove the events that get attached to the element.

            <Entity
                onMouseEnter={this.onMouseEnter}
                onMouseLeave={this.onMouseLeave}
                onClick={this.onClick}
                >

Actually, those props are from aframe-mouse-cursor-component

That is true though, we do need to detach event props when those props are removed.

An idea on that front: Store the event map as a component property (this._eventMap), then only attach a single event listener (regardless of if this._eventMap has any values or not), then inside the event listener, the event name becomes the key into this._eventMap.

We'd need to also add a componentWillReceiveProps() to regenerate the this._eventMap object, then everything else is handled without having to update anything or add / remove any event listeners.

v4.0.x will now diff the events map and register/deregister as necessary.
