- Zones now load sub scenes and acts like a "capsule" for managing everything concerning the explicit scene it's awarded. Since we have a ZoneManager around the Zones, this should be all nicely managed within the GameScreen now. - Loading two sub scenes now by default, within Zones. - Doing a stupid BoxCollider intersection test for all spawned zones. This won't work once we have more than two scenes (moving one unintelligently might cause overlap with the third, etc), so will need to move towards a smarter overlap-preventer-scheme. One step at the time though :-) - For now we set up the boundaries of an "island"/"zone" on the root gameobject in each Working/ scene.
