MYG000-98v2 Added get Years, getMakesbyYear and getModelsByMakeYear

I have added the classes to support 3 services. These services are needed on the manual-vehicle-addition screen.

/vehicle/manualvehicle/year/years
/vehicle/manualvehicle/year/{year}/make/makes
/vehicle/manualvehicle/year/{year_int}/make/{make_string}/model/models
The same.
