Next big batch of features.

-Added: Tests for IntSortedSet, IntNavigableSet.
-Added: Test Classes for: Open/Custom/Linked HashSet, TreeSets, ArraySet
-Changed: MemFreeMergeSort got improved by a lot.
-Fixed: Bugs that the tests uncovered.
-Note: TreeSets still have issues. But every other collection type is fixed.
