Add a new method to ObservableList to be able to replace a range of elements with different elements. This is highly useful when forwarding events received by a ListChangeListener to another observable list that must be kept in sync (but perhaps has its items subtly transformed). Without this method, permutations are most efficiently implemented with add/remove, but this changes the list's size temporarily (which may trigger things like selection/cursor updates). Doing in place replacements (with `set`) is also not a good option as a single large permutation event must then be forwarded as many single item set events.

Originally a request for additional setAll method with range:
ObservableList<E>#setAll(int from, int to, Collection<? extends E> col)
