My original plan was to have only those and completely ditch the Flash releases, but
openfl-html5 is not that stable yet. So I'm keeping both for now, defaulting to flash. As soon as I get sfxr working on
HTML5, I'll flip the default.
Update: just fixed a bug that prevent the
iframe from showing on Firefox. Also, added a bunch of optimizations that made the HMTL5 version much faster.
