v0.2.0

• Added benchmarks
• Rewrote everything to be further optimized (Using rope method, character peeking and just tweaks)
• true, false decode to their respective lua values.
• null decodes to a special table (qjson.NULL) to differentiate it from nil instead of being stored as a "null" string.
• Now decoding allows any sort of JSON value to be given, rather than just an object or list, as the initial object to be parsed.
