The bottom texture of non-full blocks is flipped vertically

The bottom texture of blocks is flipped vertically.
Likely the same as MC-37106, but they missed it in the fix.
Since the other bug does not mention bottom faces, and it is fixed, while this is not, I though a separate issue was needed.

Edit in 14w07a: Full blocks render the bottom face correctly, though partial blocks (such as end portal frame and enchantment table) still flip the texture.

Edit in 14w11b: Any blocks with models now render correctly, but blocks without a model are incorrectly rendering. Stairs, Enchantment Tables, and some others are still affected.

Edit in 14w17a: The only block I'm still noticing with the problem is the Enchantment Table.
