• Fixes regen in unloaded areas not fetching the previous blocks
• Fixes superpickaxe
• Fixed an NPE from history enabled edits in unloaded chunks.
• The CuboidRegion class will now queue blocks in layers for a chunk before moving onto the next chunk. This results in higher cache hits for history enabled queues. It also allows the block placer to start earlier during preprocessing with edits affecting > 64 (configurable) chunks.

Note: with fastmode or history on disk enabled, near unlimited sized
edits (for certain commands) might now be feasible.
