More functional stuff

[Arelek]

Functional: Ordered by what I think is easier to do.

1. Better mirror FOV, maybe with slider in mirrors adjust,
2. Transparent map while driving, like in convoy mode,
3. More information on navigation in trucks (distance to destination, arrival time),
4. Simple tachograph, that shows "time to rest" inside the truck,
5. Route planning, multiple cargo taken from different places and delivered to different places. Limited by the capacity of trailer,
