Found something in FastUtil i needed to address too. BulkFixes coming.

- Added: Guava TestSuit
- Fixed: HashCode and toString method would crash if the Object
Key/Value was null
- Added: AbstractTypeCollection now delegates the contains check to
type-specific Collections if it detects it.
- Fixed: Map.Entry toString wasn't writing values not like it should do.
- Fixed: Set.hashCode now is the sum of the elements instead of a Unique
HashCode based on the elements.
- Fixed: Added missing NonNull Checks.
- Fixed: OpenHashMap.containsValue implementation was wrong.
- Fixed: OpenHashMap.compute/present/absent now works how it is
specified in the Java Documentation
- Fixed: OpenHashMap.merge/BulkMerge now works how it is specified in
the Java Documentation
- Fixed: OpenHashMap.keySet.remove was causing a infinite loop.
- Fixed: OpenHashMap.mapIterator now no longer crashes in certain cases.
