Persistent and comprehensive server configuraiton #78
Description
We have formatter configuration now, which is nice, but it's a little bit clunky:
- It only covers formatters, and not all of them (missing "stylish-haskell").
- It's not persistent: you have to redo it every time your server starts. I haven't figured out a way to set it persistently (but I'm an emacs noob).
I would guess we want a bunch of defcustom variables for all the relevant configuration. Maybe we should go through the list of options the vscode extension provides and copy them over?
