Java Edition 13w01b

13w01b was released to fix some of the bugs and crashes in the 13w01a snapshot.

Changes

 * You can now shift-click rails onto Hoppers to empty Chest Minecarts
 * All containers output a redstone signal when a Comparator is placed against it directly. The strength of it depends on how full the container is.
 * This works with Trapped Chests as well, meaning it can provide two redstone signals with different causes at the same time.
 * Locked Chests texture changed with an addition redstone block.
