Key Quoting Required on json.fastfrag.org

Currently, the JSON converter and tester functionalty requires keys to be quoted, where javascript does not. This make it difficult to test JS data with quoting keys, which isn't required in the browser.

Examples.

JS is okay with

{ content : "foo bar" }

Test at json.fastfrag.org complains unless it's quoted,

{ "content" : "foo bar" } 

This is too strict.
