Automatically format JSON files according to eslint rules

[Robbert]

Formatting JSON could be useful since all files need to adhere to the same standards:

• easier to add existing JSON files, since fixing them is easy
• improve readability from JSON output of third-party scripts, such as eslint -f json
• Find tool that interprets eslint indentation, spacing, quote, curly and alignment standards
• Add gulp task fix:json

Maybe eslint --fix --no-eslintrc -c .jsonrc.json will do the trick.

Still waiting... eslint --fix is very slow indeed on a 6MB JSON file.
