This is WIP, but I'd like a few comments/suggestions on the gamesetup changes.
TODO: make this and D642 a new map xml version.
TODO: Add a script to update maps. (Also for D642, see P59)
TODO: Actually just have {} instead of { "Civ": "gaia" } since that is the default that gets used.
TODO: Make Atlas emit {} for gaia instead of null
TODO: cleanup the gui changes.
TODO: Remove debugging code (warns/commented out code), fix TODOs
