Overhaul kelp interactions.

Highlights:
- Added locking system to drops. Will be removed after testing.
- Expose more variables and functions. Will be finalized soon.
- Implement MC-like age and natural growth mechanics.
- Implement correct piston interactions with kelp and its surface.
- Implement correct falling node interactions for its surface.
- ABMs are now nonfunction. Will be fixed.
- Various optimizations and fixes.
