Python 3.x Compatibility

[laurayco]

I forked and converted to use Visual Studio, and I also changed support from Python 2 C API to Python 3.4 API. It wasn't horribly difficult to do either task, but the project is there for anybody who needs or wants it.

Cool! Did you change any of the code or is it just directory structure & build files?

[laurayco]

If I remember correctly, the only source file I changed was _jsonnet.c which I changed from 2.x compatibility to 3.x compatibility ( rather than using #defines for both ).

Would this project accept a pull request that made jsonnet compatible with both Python 2 and Python 3?

[sparkprime]

Yes, please submit a PR to google/jsonnet with the changes to _jsonnet.c. How does this work, do we distribute it via a separate pypy package?

I had a go at a hybrid python2/python3 module with a bunch of #ifdefs. It should not require a separate pypi package, since jsonnet is distributed as a source tarball there.
