Birchless

This ressource pack replaces almost every birch texture with the oak textures so every tree/building with birch looks like oak. Not changed textures are: Birch-Sign/Hanging-Singn/Boat/chestboat/shelf. Every other texture (and the item textures of everything) is changed. Birch leaves texture is changed but the color map is still the same as birch wich makes it a bit lighter than real oak leaves.
