Denis Koroskin 848bae2e95 Fix FlatUIImplementation.manageChildren() failing when moveFrom is not sorted ...

Summary:
Code in FlatUIImplementation.manageChildren() incorrectly assumed that moveFrom is sorted and moveTo is not, which is actually reverse: moveFrom is not sorted, and moveTo is. This means that we need to sort moveFrom before we can traverse it, and that we no longer need to sort moveTo (we did it by moving nodes to mNodesToMove first and then sorting it).

The sorting algorithm used is borrowed from Android implementation of insertion sort used in DualPivotQuicksort.doSort() when number of elements < INSERTION_SORT_THRESHOLD(32) which is 99.999% the case in UIImplementation.manageChildren() (most of the time this array is either empty or only contains 1 element).

Another (very rare) bug this is fixing is that the code only worked for FlatShadowNodes, but not all shadow nodes are FlatShadowNodes (there are rare exceptions, such as ARTShape, ARTGroup etc). New code works with all types of shadow nodes.
