v0.2.1

--- v0.2.1: fine tuning, improving, and adding ---

Couple of changes since v0.2.0:

• A new part category is added: weight reduction. Beware: when removing weight, the brakes become too powerful for the car and they will make the car slide, which is bad for your tires. I recommend you only choose for a weight reduction when you've chosen the automatic or 2-speed transmission, because that will enable the ABS.
• The 120 minute time limit for replacing parts is reduced to 90. It was a bit too easy for me.
• Also, to spice things up even further, you can only swap a part 5 times. Otherwise you could keep on replacing, even when a part was still good. This value might increase or decrease in the future, depending on your feedback and to my own liking.
• Several bugs are fixed, like the calculation of the prediction if the brakes could last the next race and the oil wear that kept on resetting before each race.

By the way: the cover image has nothing to do with this update, but I was too lazy to make a new one. But yes, when your brakes are completely worn, you'll see sparks flying from your brakes.
