Make code samples runnable/editable in the browser

[MasterDuke17]

At the YAPC::NA Perl 6 hackathon someone (@Util maybe?) had the suggestion that the code samples on the front page of perl6.org should be runnable/editable. I believe the glot.io API could be used for this and @zoffixznet has already implemented such functionality on his site.

Would be really nice if we make it possible not to just run the examples, but make them editable so that users can tweak them and run again. That'd be soooo cool… :)
