Did a bunch of stuff

- Made a hill on terrain for testing train with multiple carriages.
- Disabled reseting train once flipped as multiple carriages will mess
it up.
- Did some more on the attached carriages and a lot of tweaking. Still
have a lot of work to do fix in terms of making the carriages following
the train properly.
- Disabled the props for now as there are some weird objects that
obscure view.
- Made chase camera first to show.
- Randomly spawn player when game starts.
