Prepare for Elm 0.19 about elchemy

[wende]

One possible solution would be to include a binary of Elm's compiler in Elchemy (all we use is it's type checking right now) and ship it with Elchemy

In case elm-github-install gets discontinued we could inherit the package. As far as I understand we can still use it as long as the elm-package.json name get's changed to elm.json. If it's discontinued it might even become elchemy.json as far as I'm concerned

The only part which is really heartbreaking is to see elm core team backstab the community yet again

This is a great summary of minor changes: https://korban.net/posts/elm/2018-08-22-elm-019-whats-new-install-upgrade/

We're staying with 0.18. Whenever you try to use Elchemy with 0.19 it will ask you to use correct Elm version.

Until we develop our own type checker we will run on Elm 0.18 only

@passiomatic Thank you! That already outlines a lot that's very important and I haven't seen mentioned anywhere

Turns out things are much more complicated due to:

0.19 means they are technically entitled to that, but yeah, I see your point.
