Update to KCSG version 2.0

• FactionSettlement can no longer be used as a defModExtension. Replaced by CustomGenOption.

CustomGenOption

• useStructureLayout no longer needed and removed.
• shouldRuin no longer required and removed.
• ruinSymbolResolvers renamed to symbolResolvers.

FallingStructure

• weightedStruct tag renamed to structures. It's filled with li:

<li>
  <layout>Def</layout>
  <commonality>1.5</commonality>
</li>

GenStep_CustomStructureGen

• shouldRuin no longer required and removed.
• ruinSymbolResolvers renamed to symbolResolvers.

SymbolDef

• Terrain related tag are no longer used and should be removed (isTerrain & terrain). This mean all terrains symbolDefs need to be removed.
• Removed obsolete lordJob tag.
• Pawn and corpse symbols are now auto generated (it is still possible to customize them).
• Now fully work with VE mountableOnWall.
• Added a replacementDef tag. It allows defining another def to be used if thing couldn't be loaded (DLC/mods things). It should be something all users can have access : one of your mod thing, or a vanilla thing.

StructureLayoutDef

• Layout terrains should now be in its own tag: terrainGrid. If upgrading an old layout, you can copy the li in layouts that contains terrains names (usually the first or second li).
• Layouts can now be tested right after export (without reloading the game) with the "Quickspawn temp structure" debug option.
