Now every zone can be surface, underground, or both. This is separate from water <-> land distinction.
Iand type is now a combination of flags and can take multiple values: "type": ["LAND", "WATER", "SURFACE", "SUB", "ROCK"]. In nothing is specified, terrains get LAND | SURFACE flags by default.
Non-surface zones will default to DIRT, and non-underground zones will default to SUBTERRA.
