New:

• Custom block breaking, utilizes value of BlockProperties#hardness
• CustomTool component, behaves similarly to Tool component but for custom blocks
• compress config added to resource-pack section, by default true, currently minifies all json so useful for packs with alot of models
• FakePlayer and OfflinePlayerData APIs for modification of players that are offline and also using that data for fake players

Changes:

• Resource pack server has been optimized a bit
• external-packs field now supports {"path": boolean}, this allows for exempting external packs for compression (required if pack is compressed OR encrypted)

Fixes:

• PackServer will no longer duplicate packs for client (uses deterministic UUID for packs now)
