> Add JSON.pm to third_party

> We're using JSON as an exchange format both:
> 1. To make the existing Perl more modular
> (so we can connect the parser and code generator via intermediate files),
> 2. To ease porting to Python, so we can connect existing Perl scripts
> to new Python scripts.
>
> This is build-only: the module is used during the build, but not included
> in the distributed binary, and thus should not pose licensing problems.
