Web build added

Been waiting for the results of the jam. Happy enough with the score I received but sadly didn't get any written feedback. Sounds like that may have been due to the desktop builds needing malware testing before being judged.

So today I've updated the page with a web build. I couldn't get it to work during the jam itself, but I've now discovered I just needed to set the export name to "index.html" rather than renaming the .html file after exporting.
