New Features and bugfixes.

- Fixed: AbstractCollection bulk adding methods now link to the
specialized implementations.
- Fixed: A bug with getElements in ArrayList.
- Fixed: PriorityQueue remove/toArray function were renamed so they fit
better with other interfaces. (remove => removeFirst and toArray uses a
different genericType)
- Added: LinkedList which is a List/PriorityDequeue/Stack which allows
for more optimized use-cases and reduced boxing/unboxing.
- Added: Tests for LinkedList
