*: huge overhaul
1. the INDEX PAGE was broken for so long, but I really could not have been arsed to fix it.
2. all major css has been moved to css/style.css
3. png files are now all jpg files because having pngs on a website is overkill
4. update libopenmpt, not sure if it works (local JS doesn't work on my browser)
5. libopenmpt is now the JS-only version because browsers like pale moon still don't support
