Pseudo Random Tour 1.5.2

This is a minor update that includes the following:
- Allowed the T-series truck to be selected again by the mod (this was previously denied, due to a bug with BeamNG where spawning in a T-series would prevent being able to drive it).
- Clarified what the "driveability" means in the info panel as it was a little unclear and suggested it was a selectable thing you could change; for the avoidance of doubt, it is simply a description of the road quality for a generated path
- Fixed the route driveability metric always returning 0 for generated paths
