A few bugs in 14w32d

There are a few bugs as seen in the screenshots:

1. The torches on the End Portal that spawns once you kill the ender dragon do not connect to the Bedrock, as a result it looks weird.

2. You can place torches on Stairs (on the actual stair part) but you can't on the back of a stair.

3. The break animation on some blocks renders weirdly (such as redstone ore, chests, signs, etc.
