ETS2 - Volvo FH 2012 Realistic Dashboard (1.39.x)

Changelog:
Update for 1.39.

Maybe this dash is not "realistic" but it looks like a "realistic", but I change places of some info and added something like a current speed at main central display.
Also added instant consumption bar and average consumption bar on trip info display with trip travel time and trip average speed.
