Dirt Sorter - Stone production

Use with "TerraFarm" mod.
Since dirt can not be sold on most of the maps and digging up stone fill type with "TerraFarm" brings you way too much money I decided to convert this mod. The idea is to dig up large amounts of dirt with "TerraFarm" and sort stones out of it, then sell for profit. To make it more realistic you get 200l of stone per 1000l of dirt.
