Changes the recipe for landfill to be more expensive. This will make it far more difficult to fill in entire seas or bridge across waterways. (Forked from https://mods.factorio.com/mod/ExpensiveLandfillRecipe)

1) gravel was added to this mode as intermediate substance, for the main purpose - complicating the production cycle
2) As far as I know Factorio - all water is shallow. Factorio din't know difference between spall lakes and biggest ocean waters
