Currently, the Civilization Overview pages (i.e. {civ}.json files) are filled with false information. A lot of the mentioned features aren't part of the game and some mentioned bonuses are plain wrong. Moreover, information on many things that are specific to civilizations in 0 A.D. is absent.
This patch corrects and updates all the {civ}.json files:
* Non-existent technologies, civ bonuses, and structures entries are removed.
* Incorrect technologies, civ bonuses, and structures entries are updated.
* Missing technologies, civ bonuses, and structures entries are removed.
* Structures use the generic name (i.e. common English name) rather than the specific name (i.e. ancient language) for the Name fields.
* The "Armament", "Class", "Emblem", "Phase", and "Requirements" fields of individual entries are purged, since they are not used, and unlikely to be displayed.
* The "Special" field of structure entries is renamed to "Description", like the other entries, so it's actually displayed in game.
