Removed emscript demo since not up to date

Taking in an extern demo is almost always a bad idea since I will be
the one to keep to date and I am not always able to do so. Emscript
was the last time I tried. For now on if anyone has a neat demo
please keep it in your own repository and I will create a link to it.
