Demo update

I have been updating the demo with small bug fixes. This update is different, on top of fixing more bugs I have added two new gameplay mechanics:

• You can now apply special upgrades on your custom parts. Contrary to automatic upgrades, a special upgrade focuses on a specific characteristic and can be greatly beneficial. You also decide how many races you want to spend on a special upgrade (the more time you spend on one, the more likely it is to succeed).

• If you are supplied by a manufacturer (which is not another team on the grid) you can also now periodically vote for a special upgrade said manufacturer should apply on the part they supply you with.

Engine manufacturers also are now more likely to offer existing teams to become their factory team.

I have also updated the background images used when displaying news headlines.

That's it for now, see you soon!
