Memory leaks in DataStore

[pilwon]

There is DataStore.saveFamousFrameworkComponent to register key to COMPONENTS object but no function exists to unregister key from it. This causes a memory leak problem over time in any component that uses $ifs and $repeats where children nodes are dynamically added/removed. We need a destructor function that knows how to reach in to these places and clean things up.

Thanks for bringing this up @pilwon. I will work on putting in a deregister method and calling it in the appropriate place.
