these lists should be loaded from the GDX similar to what is done in the main reporting:

another question: why do we need to unify tkm/pkm -> km? Since these values mean quite different things they should in my opinion be reflected in the unit.

[johannah-pik]

I changed it for compatibility with REMIND compareScenarios2 and I think it makes things a lot easier if you do not have different units for freight and passenger energy services as long as our definition is clear on that (vkm are still vkm and km is either tkm for freight or pkm for passenger)
