Add version index (#461)

leebyron · Travis CI · commit 8b9d3519abf8 · 2018-06-10T15:58:38.000-07:00
Replaces out current index redirection script with a file which lists out all published and pre-released versions and no longer redirects automatically.

Additionally, this retains the current hash so old links can be easily followed through to the intended spec version.
