Added a "strict JSON" mode to the text generator and compiler

Browse Source 
This will add quotes around field names, as required by the official
standard. By default it will leave quotes out, as it is more readable,
more compact, and is accepted by almost all JSON parsers.
The -S switch to flatc turns on strict mode.

As per rfc 7159.
