Processed wood (smooth wood)

I think a smooth variant of wood would be useful in building and would complement the plank and striped varerants. This vareant of wood will be weaker and more flammable than the other vareantts. As this wood varerant is processed it will be able to be made into stairs, slabs and walls. This can be crafted with 9 wood planks of the corresponding wood. This will be usesfull in many building situations alongside the striped and planks vareantts.
