Title: Remove SBJSON and use NSJSONSerialization exclusively

This pull request removes SBJSON entirely and replaces it with NSJSONSerialization. This restricts deployment to Mac OS X 10.7+ and iOS 5+.

I realize this may not be the direction you intend to take JSON support in the framework. (I see in the preview branch you have renamed SBJSON).

That said, NSJSONSerialization outperforms SBJSON handily and is guaranteed not to conflict with any JSON libraries the user may be using with different versions. For applications that do not need to support older deployment targets, it is an appealing option, and this pull request can provide it. :)
