Beta Used Car Generator 0.8.1

This is part 1/2 of the full release update, focusing on quality of life improvements, bug fixes and performance improvements.

- Added a new part: Torque Converter; A worn torque converter will have less locking torque. A nearly broken one will slip a lot and cause the transmission to shift erratically sometimes.
- Added support for imperial length units
- Major optimizations and performance improvements
- Reduced Automatic Gearbox wear at high mileage
- Overhauled the UI App, it is much more flexible and fixes many alignment issues from the previous version
- The show seed option now shows both the Spawn seed and the Condition/Wear seed
- Renamed the "Seed" setting to "Wear Seed" to be less confusing with the other "Generation Seed" setting
- Removed the paint wear effect that makes the color grey at low condition (it didn't feel quite natural imo)
- Fixed paint wear not using the previous wear seed when requested
- Fixed several Error/Success messages overlapping and made them easier to understand
- Fixed several bugs with the Vehicle info/state interface:

• Significantly reduced loading times
• Should no longer load infinitely or give false results
• Should no longer reset when interacting with BeamNG menus
• Should now always know when an error has occurred
• Should no longer have underscores instead of spaces

The full release update will feature a revamped wear algorithm system, new settings and more bug fixes. Stay tuned!
