Lots of fixes, tuning tweaks and more in this update.

• New car: Throw your roll cage around in the stripped-down, souped-up Dune Jumper.
• New track: Finally you can jump the shark (har) in Shark Harbor.
• Can now turn Character ability to 0 in game settings. That means you can have a pure driving skillz race with no powers or powerups.
• Tweaked Balanced powerup mode. Now with more Balance!
• Reduced speed penalties from breakables. (Ian and Ralf think we're all wimps).
• Tweaked chances of Double Powerups vs Fast Powerups as the race draws ever closer to its exciting conclusion.
• Added a "Defaults" button to the game settings.
• The AI can now boost start. And fail boost starting. And sometimes do nothing.
• Upgraded to Steamworks SDK 148a.

We also changed some winner-whackers Powerups back to globals. We're still tweaking all of this so please let us know what you like and what you don't!

• Big Tires - because bouncing is fun
• Donut Tires - because frosting is effective
• Earthquake - because earthquakes are for everyone
• Nitro Car - because bombs

As always we welcome your feedback. Thanks everyone!
