Gravitational Racing 1.3.5.2

Just a few more fixes and changes:

• Fixed textures being overwritten (as far as I know at least - I couldn't replicate this problem again)
• Also fixed orange key having a missing texture
• Updated the hub-world platform - each scenario is a circle and bridges are less pointy + less likely to eat your car
• Stopped starting Jupiter moving around until scenario starts in Planetary Perils - makes it less waiting for it to pass to start the scenario to not lose time

I have been made aware of the fact that BeamNG has an N-Body system for dealing with celestial bodies so I'm going to try and see if I can move over to that system instead of wind. Also, I have some new scenarios planned with new celestial types + challenges though I still need to finish an update to my Car Games mod first
