Ensure `api.archivers.co` is a useful root endpoint

[patcon]

Currently api.archivers.co points to a page with only the response:

{ "status" :  "not found" }

It would be great if this went somewhere more useful. Potential options are:

1. redirect to /docs UI
2. provide a summary of all the top-level endpoints like other api sometimes do

My personal feeling is that (1) is more helpful, but curious to hear others' feeling.

Note: I'd like to convert this into a first-timers-only issue once we have a clear path forward.

yea yea yea! I'd prefer the root endpoint to return valid json if at all possible to maintain consistency, so what about a JSON message that indicates the API version & docs link?

{
  "message" : {
    "apiVersion" : "0.1.0",
    "status" : 200,
    "docs" : "https://api.archivers.co/docs"
  }
}

This frees us up to move the docs endpoint to somewhere smarter later on (eg: inside a bigger source of help & documentation)

I see we're using data, meta, pagination. Are we conforming in whole or part to jsonapi spec? http://jsonapi.org/format/#document-top-level

If so, should the impementer look to that spec instead of message? (I feel it can be left as an exercise to the implementer to sort out how the solution might conform :) )
