More fixes.

- Fixed: containsKey & containsValue in HashMaps were deprecated for
Object Variants.
- Fixed: HashMap wasn't deleting Keys & Values references when removing
a Object
- Fixed: AVLTreeMap didn't balance properly.
- Changed: EnumMap no longer tries to access SharedSecrets since its
gone in java11
- Added: HashMaps now implement ITrimmable
- Added: AVLTreeSet didn't balance properly
- Fixed: HashMaps & LinkedMaps weren't clearing references properly.
