Just a couple of fixes and some misc features:
- Added in an option to keep the current vehicle for the next route
- Added in an option to only generate the last waypoint of a route, allowing you to go about it via any way you want (distances and road-indicator will not be very accurate)
- Fixed being able to start the scenario before a route is geenrated, if the scenario is reset
- Change the name of the route length to "approximate" - from recent changes to better lapped-routes...
