NOTICE: This version removes the OLD WOOL STAIR, OLD CUT COPPER & OLD CHISELED RESIN BRICKS, these were only in the mod for one patch a few months ago and only about 40 people downloaded the mod when they were craftable, please make sure you're using the new block versions before updating.
Stairs_SimpleUV.blockymodel instead of Stairs.blockymodel, this removes the need to have a separate "stairs" texture and all stairs now use the base block's texture. (For example MC_Oak_Stairs now use the MC_Oak_Planks' "oak_planks.png" texture instead of it's own "oak_plank_stairs.png" texture), this reduces the mod size by about 0.1MB overall. This should also fix an issue with textures on corner stairs.
