Use JSON3 instead of JSON2 library

We recently started using the JSON3 library as it

1. Correctly serializes primitive wrapper objects.
2. Throws a TypeError when serializing cyclic structures (JSON 2 recurses until the call stack overflows).
3. Utilizes feature tests to detect broken or incomplete native JSON implementations (JSON 2 only checks for the presence of the native functions). The tests are only executed once at runtime, so there is no additional performance cost when parsing or serializing values.
