more variations of diorite, andesite and granite blocks

they really lack some other block materials like basalt or blackstone, if it was added it would give them more variety and I guess usefulness including variants like: bricks broken bricks chiseled tiles pressure plates buttons all furnace types all the other variants (normal and broken bricks and tiled) as stairs and slabs walls the stone cutter and a few of the redstone tools that have stone in their recipe, if not then just add a way to craft them with these materials that's all
