New version(s)

[alanz]

FYI we now have https://github.com/haskell/haskell-ide-engine/releases/tag/1.4

But to add complexity, we now also have https://github.com/haskell/haskell-language-server/releases/tag/0.1, which should have basically the same packaging process as hie.

I am not sure if that belongs here, or should be somewhere else?

With #64 merged HIE was updated to a recent unstable version (after 1.4)
