HTML5 early export test

So, because Juan came out with a revamped HTML5 exporter template we gave a try. On a modern pc initialization time is accetable, game performances are good. Unfurtunatelly there are a plenty of quirks in render: lacks of shadows, rigged model are not visible, no cube map as background, particles are rendered oddly, viewports are not working, anyway, as starting point is very promising. Juan staded he will work next months on fixing issues in that platform.
