Add event which fires after fade animation is complete

[paaatrick]

I'd like to do some cleanup work after the modal is completely hidden. I tried using the $.modal.CLOSE event, but changes made in that event's callback are visible while the modal is fading out. Here is an example: http:https://jsfiddle.net/p4o3ycew/1/

You can see that the title goes blank as the modal is closing.

Perhaps an event like $.modal.AFTER_CLOSE could be added which fires after the fade animation is finished.
