I want this! It should:

1. Run hoogle with the right database according to the stack config in the directory in which it's run (so it's easily ran from a terminal or by IDEs).
2. Automatically download the hoogle database from stackage.org e.g. https://www.stackage.org/snapshot/lts-2.1/db.hoo for lts-2.1.
3. Put it in some reasonable place like ~/.stack/hoogle-databases/lts-2.1.hoo.
4. Or when running inside docker, use the hoogle database provided by the docker.

The last docker point means we probably need to sync up some things.

With this command I could provide some nice Emacs support with a live hoogle search buffer, and I'd basically never have to leave Emacs to open my browser to read docs again. This closes off two big pain points for me: (1) always having to open the browser and leave my editor environment, (2) needing an internet connection to view docs. This will also basically make my whole haskell-docs package redundant which I'll be able to deprecate in favor of stack.
