[v1.5.1] Impossible Levels Fixed (General Improvements)

Happy August - Here are some fixes:

• Some tracks were impossible with the default car, fixed those now. Let me know if you spot any more?

• The UI was really tough to see when you were done racing, so I fixed that.

• The Garage manager didn't order the cars by their value, that's resolved.

• When the resolution was higher, the garage didn't center the text.

• Some of the thumbnails for the levels were wrong, updated those now.

Thanks for Racing!
