Lite Collections for ActionScript Fx Code

[DEV] Added a children filter to IRecursiveFilterIterator to be able to skip children of particular items in recursive enumeration

[DEV] Renamed event kind FxEvents.COLLECTION_REPLACED to FxEvents.DATA_SOURCE_REPLACED

[BUG] Subsequent calls to getNext() without a prior hasNext did fail in RecursiveIterator, if the current child iterator had been finished in between.

[DEV] Added bulk operations to IArrayList and its implementors to increase performance
- addItemsAt(index : uint, items : Array);
- removeItemsAt(index : uint, numItems : uint);

[DEV] Renamed sortList to sort in ArrayList

[DEV] Added ICollectionFx interface to mark collections as bindable.

[Bug] Added missing event after ArrayListFx.addItemAt(index).
