Sooner or later we're gonna have to do it the hard way. I think it's a must to fork gh-pages and convert it to TypeScript.

a) consistently use ts and async / await everywhere
b) merge that PR to support #46
c) remove use util.debuglog() again (see tschaub/gh-pages@380a9ae) which requires ugly monkey-patching on our side

Anyone who wants to help out is welcome to contact me. That's gonna take some work!
