Started massive unit testing library these are the first fixes.

-Fixed: AbstractCollection.retainAll didn't push removed values through the consumer.
-Fixed: AbstractCollection.toArray wouldn't reset the last entry if the input array was larger then the elements in the collection.
-Fixed: SubList didn't check for ranges properly or didn't use parent list to validate changes.
-Fixed: ArrayList.addElements didn't check input array fully and used the wrong variable to move the elements around.
-Fixed: LinkedList.addElements(EmptyInput) would crash.
-Fixed: LinkedList.swapRemove didn't account for if the removed element was the prelast one.
-Fixed: LinkedList.removeElements would break the implementation if the list was almost empty and the middle element was removed.
-Fixed: LinkedHashSet.addAndMoveToFirst wouldn't move elements to the first place.
