0: original networked test with 1-byte nodes
1: update with 2-byte nodes
2: lighting is transmitted in param
24: 16-bit node ids and node timers (never released as stable)
25: Improved node timer format
26: Never written; read the same as 25
+ 27: Added light spreading flags to blocks
+ 28: Added "private" flag to NodeMetadata
