JSON Support in the Sandbox

I have added JSONParser & friends to the sandbox. The code was ported from JSON Parser. At first, I intended to wrap the library, but things got really messy, so I decided to pull out what I need and tweak it into a more tidy codebase. Experience was a nice reminder of why I have evolved from C to C++ (flames welcome ;-). At any rate, I’m quite satisfied with the outcome and if anyone has use for this, please do some testing and give feedback. This is just an initial approach and I have only compiled it on Windows w/ VS 2008.
