General

 * NBT tags
 * Added an NBT tag that can lock containers.
 * Mostly useful for (adventure) maps in adventure mode.

 * The lock can be cleared with the command.
 * Locked containers can only be opened while holding an item renamed to the given string.
 * Example: If the value of the Lock tag is "Key", a player will not be able to open the chest unless they are holding an item named Key.
 * Item is not removed on use.
 * Only works if the item has a custom name (default names will not work).
 * Example: a chest with the tag  cannot be opened when holding a diamond; the item held must be renamed Diamond.


 * Splashes
 * Added "That's Numberwang!"

Blocks

 * Anvils
 * The cost of experience is now reduced.
 * Renaming items will now only cost 1 level, repairing will now start out with 2 to 5 levels and tools can be repaired longer and with better enchantments, repairing costs can no longer be kept down by renaming items.

 * The first time a specific trade is done, the villager will become willing, any other time there's a 1 in 5 chance the villager will become willing.
 * When a baby villager is born, both parents lose their willingness.
 * Finding out a villager's willingness in survival is difficult: The only way to tell is the amount of XP they give when trading; Normal trading yields 3-6 experience points, trading and making a villager willing yields 8-11 experience points.
