Realistic Block Physics

Note: Some changes require regenerated config files to take effect.

Fixes

• Fixed an error that could occur due to non-existent chunk data when performing chunk analysis
• Fixed an issue with extended block collision bounds not using relative directions for blocks that do not have any collision bounds
• Fixed blocks with a block definition, but no collision bounds, causing the ground beneath them to fall if there is an air pocket
• Blocks that land in liquids no longer "break" them
• Fixed the default physics for fence gates, so that they can now remain attached to blocks when opened [config change]

Improvements

• Further improvements to falling block relocation logic
• Amendments to filtering out blocks, such as flowers, bushes, and liquids, when applying default block definitions

Changes

• Changed the default "wood" block definition to specify logs via IDs instead of tags, as a temporary solution to Dynamic Trees compatibility issues [config change]
