There was an issue with visualization

[yhbest]

We build blackly-games through wiki's guide.
However, when we opened "maze.html",
visualization didn't work(look at screenshot), script was missing.
and the "Run Program" button didn't work either.

I build it on El Capitan and I used Safari browser.

Thanks for helping :)

I believe that this was fixed in the February update. Prior to that the build was quite broken.
