Maintalbahn Track Rule Mod

This mod edits the track rule assets of the Maintalbahn route. Modifications are as followed:

1. Changed Vmax (permitted maximum speed) from 120 km/h to 140 km/h. (140 km/h is allowed Vmax of the DB BR 218, so I thought why not? :P)
2. Changed Track Adhesion from 1.0 to 0.85 (make tracks less adhesive)
3. Changed Track Unevenness from 0.25 to 0.6 (make tracks more uneven)
4. Allow german electric locos (15kV, 16hz) to run on the tracks in Free Roam mode. This could be done with GodMode before, however setting a path may didn't work in this way due to the diesel-only track rules.
   (This does not affect diesel traffic in the timetable in any way, just provides players the opportunity to run more locos on diesel tracks since we still miss a lot of diesel locos in the game unfortunately)
