Minecraft Snapshot 18w03b

A Minecraft Java Edition snapshot

This weeks snapshot brings some performance boosts for data pack loading & command execution. We're moving offices next week, so there may a bit of silence surrounding snapshots as we settle down and figure out where the new best pizza place is. Priorities, you understand.
