Embed Parrot into Google Chrome via Native Client

This seems to allow arbitrary native C/C++/etc code to be run in the browser.

If we write a NativeClient plugin that uses the new Parrot embed API, that would allow people to run Parrot directly in their browser.

I compiled now my nacl toolchain following https://github.com/zerovm/toolchain/blob/master/README.md
We probably should define some sandboxing environment, disallowing local file access, process and os access.
Only stdin, stdout, stderr.
