Making it look prettier

Since this is a game out of a jam, made in just a few hours. The games was really ugly, it is still ugly but I tried to improve some aspects:

• Camera reworking. Reworked the camera to give it more movement... 
• Nicer car models. Previously I had only one model. Created several models to generate more diversity. Thanks Asset forge!
• Generated pseudo buildings. This will help on creating the sense that it's actually a city... 

This didn't change gameplay at all. Probably I'm going to address that in the near future. 

If you have any questions or feedback let me know!
