NOTE: The goal is to increment this so that saved maps will be
loadable by any version. Other compatibility is not
maintained.
Serialization format versions:
== Unsupported ==
0: original networked test with 1-byte nodes
1: update with 2-byte nodes
== Supported ==
2: lighting is transmitted in param
3: optional fetching of far blocks
4: block compression
5: sector objects NOTE: block compression was left accidentally out
6: failed attempt at switching block compression on again
7: block compression switched on again
8: (dev) server-initiated block transfers and all kinds of stuff
9: (dev) block objects
