Use SBJsonParser/SBJsonWriter instead of NSObject+SBJson

Browse source 
- SBJsonParser can be used standalone when JSON posting is not used
- No NSString -> NSData conversion when encoding
- Possibility to implement error handling (although [parser/writer
error] returns a NSString...)
- Documented interface:
