 * A way to lock containers from being opened using NBT tags
 * Mostly useful for adventure maps in adventure mode
 * NBT Tag in JSON format:, containers can be unlocked by clearing their string for Lock (changing it to  )
 * The lock can be completely removed utilizing the command {{cmd|blockdata}}
 * 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

 * Prevents accidentally changing the difficulty when joining the world
 * Locking can not be undone

Fixes

 * – Villagers ignore damage values and item tags in trading
 * – Players can place and remove arbitrary blocks in Adventure mode, breaking pre-1.4.2 maps
 * – Random destination routine has a small statistical tendency to move more north west (fix included)
 * – Clicking hotbar hotkey (1-9) to move a stack of items / blocks to enchanting table deletes all but one of a stack
 * – Zombies kill villagers instead of transform them (HARD difficulty)
 * – Chicken Jockeys causing lag on Multiplayer servers
