* Implemented new ObjectAccessor functions: GetCreatures, GetUnits, GetGameObjects, and GetWorldObjects. These can be used for loopong over objects in the world.

* Note: GetWorldObjects is (probably) heavy and should be used very sparingly. Always use the function corresponding to the type of object you're looping over.
