 * Locked containers can only be opened while holding anything renamed to the given string, item is not removed on use
 * The lock can be completely removed utilizing the command
 * BlockItem instances can now hold a custom NBT tag that is merged into a block entity when it’s placed
 * Example:
 * Gamerule
 * Prevents command block output from being stored in chat logs. In multiplayer, also prevents player-initiated commands from being stored. Unrelated to commandBlockOutput, which is output into the visible chat.
 * Scoreboards
 * The ability to reset objectives one by one

 * Fake players with a name starting with # will never show up on the sidebar
 * New subcommands:  and
 * The  subcommand can apply arithmetic operation to scores (+ – * / %) and accumulate player scores
