SkyboxManager 2.0 + Bugfixes III

-Skyboxes will now only change when Mathius enters the Transition wall
(BoxCollider)
-Added a property to Map Properties to set whether to use Day/Night or
Default map cycle. This should fix the Skybox Day/Night effect on the
Moon.
-*Consecutive maps have their SFX played only once
-*Gameplay without Perceptual device fixed, this was causing issues with
how Mathius moves.
-*Readded Perceptual Components to the brain. Thinking about possible
default setting to false if Perceptual fails to render.
-*Deleted multiple instances of volcano.

* = Verified thru gameplay.
