Re: PoC: Browser based runtime

Though, after a day of experimentation with various options, it seems
like https://github.com/annulen/webkit might be the way forward. It
seems to work well on mac and solves the issues we had there
previously.

Next step would be to see if the runtime will work on Windows if
compiled with Mingw and linked with a VC 2013 Python. I suspect it
will...
