New utility blocks and villager professions

The Smelter, a new furnace type block that can smelt everything a Smoker and Blast Furnace can't, such as clay to bricks, sand to glass, blocks to smooth/cracked blocks cactus to green dye, every Furnace exclusive smelting recipe, all at a faster rate.
The Woodcutter, a Stonecutter for wood blocks.

Crafting recipes can be a furnace surrounded by... cobblestone tier blocks for the Smelter I guess? And an iron ingot surrounded by 5 wood planks, and 3 slabs for the Woodcutter.

The Lumberjack Profession for the Woodcutter can trade wooden tools and items, like a Leatherworker trades leather items, and the Smelter Profession trades you items like single bricks smooth stone, smooth sandstone, cracked bricks, maybe even dyes and dry sponges at the highest levels.
