Long Truck 1.4 (final?)

This the final (???) version of Long Truck. Now with Scoreboards!

Changes:

• Time limit: Now you have 15 minutes to reach the target location
• Magenta Spheres: There are now magenta spheres, those are worth 5x more than regular blue spheres.
• Scoring: The final score will be 100 points for each blue sphere, 500 for each magenta sphere, and 1 point for every second left on the timer before reaching the target.
• Parks (green squares) have been removed due to collision issues and spheres have been put in their place.
• It is now harder to tip the truck, and the shape is no longer a cube to make it easy to distinguish the front of the truck.
