ipyrad rtfd 'latest' doesn't point to current docs

This is annoying. If you go directly to rtfd the default branch is master and the docs are up to date. If you google 'ipyrad installation', the first link points to 'latest' which actually is far out of date. Can't figure out how to point latest to master.

In order to fix the rtfd integration so that it auto-builds docs like it did in the old days we need to set up webhooks, which only the repo owner can do. Manual config for rtfd/github integration instructions.
