Revamped the way BodyObject.location is tracked. Now we use an object which can

be extended to contain the sceneId by Whirled (Vilya's Whirled, though also
Whirled Whirled by extension) so that we don't end up with problems where
BodyObject.location changes but BodyObject.sceneId remains stale. This won't
impact Yohoho because the Yohoho client is always in a scene, it uses a
separate mechanism to track games, whereas Whirled's natural usage is to move
between scenes and non-scenes.
