use oportunity to add at least polished versions for forgotten stones

basalt, but especially amethyst and calcite deserve polished/brick or even chiseled variants, if sulfur gets bricks and polished variant, why calcite has none yet, it has no crafting use and since it is only in its "natural" form, it is also limited as building block
basalt isnt as desirable in my opinion, given plenty of gray bricks exist already, but calcite would have unique color for bricks, closest being endstone, which is still not really white, amethyst should have at least polished/cut variant to look nice and smooth
