Update transportation.js
Update transportation.js

Made the functions match the INL transport costs.   There were a few errors: 1) loading/unloading was calculated on per acre basis not per ton 2) truck O&M (collection.OIL_ETC_COST) was not multiplied by distance traveled and 3) loading cost added TRUCK_LABOR when it should have multiplied by TRUCK_LABOR.
I also revised the descriptions to be more accurate.
