An Intamin accelerator layout

I've made some more progress on my Intamin accelerator coaster. I've changed the track model again - since I now have a track model that matches the vanilla giga coaster, I have modelled a 4 rail track based on that. The new one is less accurate to the real world dimensions but fits the game better.

I have also implemented the ability to switch between 2/3/4 rail track during construction, and I've started implementing a magnetic brake piece, which is fully functional though the sprites need some work. I have created a model/initial sprites for the launch but this is not yet functional (well, it is, but it just works like a booster at the moment)
