D-up 029

Updated several aspects for v0.8 (new powertrain) support:

1. Refreshed all included configurations for new official powertrain components.
2. Refreshed all four included Pickup frames based on changes made to the Pickup in v0.8.
3. Replaced the "Heavy" lifted Roamer frame with a standard lifted Roamer frame for now. Again, the current frame is based on the updated Roamer frame released with v0.8.
4. Fixed included "wheel spacers" to function with the drivetrain update.

If I missed anything I'd appreciate a post about it in the forum thread: https://beamng.com/threads/d-up.31344/

Have fun!
