Camera moveForward/moveBackward broken in 2D view

[thw0rted]

Go to the Sandcastle demo for Camera control, switch to 2D, and try the W/S keys. The camera moves toward or away from the map in 3D and Columbus, but does not move in 2D.

I just noticed that ScreenSpaceCameraController uses Camera.zoomIn instead of moveForward. This works fine.

@thw0rted OK to close?

Well, at least somebody should update the demo to pick the function based on the mode, but also I don't think that moveForward should have no effect at all in 2D mode.

@thw0rted if you have the time, it would be great for you to open a small pull request to update the Sandcastle example, thanks!

It would be simple enough to update the example, but I do think that moveForward should be fixed to move toward the map in 2D mode (which would make the Sandcastle update unnecessary).
