ORTS Diesel Engine Parameter loading depends on loaction in eng-file

If you combine MSTS and OR Diesel Engine Parameters, OR uses the OR Parameters in dependence of the location in the eng-file.

Example:
If you only want to add a Diesel Engine Power Tab like
 ortsdieselengines
 ( 1
 Diesel(
   dieselpowertab(
    0 0
    400 500hp
    750 933hp
   )
  )
 )
to MT_DD_CLASS_27_27102.eng of the example material, it will be recognized by OR, if it is located e.g. as the last entry of the eng-file. Then missing OR Diesel Engine Parameters are replaced by existing MSTS parameters, as it should. If you add the same Power Tab e.g. below the MSTS Sanding Parameter, it does not work. It's resulting in zero engine rpm, power and tractive force.
