aetherjs.com not working

[kssgsw]

tried to get some infos on the project, the website is broken seriously

At this point, https://github.com/codecombat/esper.js does most of what Aether used to do, much better. Aether only pulls in additional parsers/runtime for Python/Lua/CoffeeScript and is kind of in a sorry state. Should probably update the README for that, and unlink the aetherjs.com site, whose GitHub page is busted.
