New Holland T9 Improved - Fixed v2.0

- Added configurations for the T9.435, T9.600, T9.645, T9.700. The configurations also have appropriate horsepower and torque.
- Added more tire configurations, 900 singles, 800 and 900 duels, 520 triples.
- Added fuel tank size configurations. They last 6, 7, and 8 hours respectively.
- Prices have been adjusted to be more realistic (and as such more expensive.) Tires are now way more expensive and engine configuration prices are also scaled up.
- Fixed the holes in the hubs for the added tire configurations. Adjusted a few things.
