use either large or small stone
Suggestion: how about instead of having to convert all stone to small stones, a recipe would just require either 25 small stones or 5 large stones, for example. Or whatever the right amounts are. We already have recipes that can take any kind of metal, for example. I know this suggestion increases the complexity because that introduces different amounts, not just kinds, but it has to be better than this tedious conversion of stone thing we have going. I'll have to check and see if the stone crusher mod works with .7 now.
