[Car Builder] Intermediate Visualisation Layer

[PMP1337]

I think it would be nice to have a layer of visualisation between full car and car without body.
A Visualisation layer that just removes the hood so that we can see both the full car and also a glimpse of the engine in the engine bay.

It's nothing really core but it's nice for pictures and screen-shots.

Check out the vertical slider bar on the right side of the game screen it's already there.

There isn't one with no bonnet though. We want to add that, it'll be easier when we go to unity.
