D1953 standardizes the formatting style of the technologies json files. This one does the same for auras. Changes:
* spaces inside brackets, e.g. `[ "Ship" ]` instead of `["Ship"]`
* use tabs for indentation, not (two) spaces
* alphabetize modifications, except for damage types and resources, which have a fixed order (hack, pierce, crush and food, wood, stone, metal, time, xp, respectively)
* remove unnecessary trailing zeroes
* aura descriptions per https://trac.wildfiregames.com/wiki/EnglishStyleGuide :
* B.C. → BC
* HP → health
* the Meroë Empire → Kush
* proper quotation marks inside `wonder_pop_2.json` description
