Title: Use JSON.generate to properly quote JS string

`JSON.dump("string")` fails as JSON can't have a string at first level (it should be an object or an array). `JSON.generate` in it's turn allows to pass [options][1], so we can enable quirks mode to use JSON as a string escaper.

Notice that although `JSON#generate` has no info about quirks mode, it uses [Generator::State][2] which has detailed info about possible options.
