The removed modules are literally not imported anywhere, so removing them has no effect.
I may have missed some.

This executable is not referenced in `gargantext.cabal`, and as such,
it is never compiled.

Some files in `src/` contain Haskell syntax, yet have the wrong extension
(`.sh`, `.purs`, `.old`, `.hs.old`). They are not picked up by Cabal.

They were most probably saved with the wrong extension by mistake,
and forgotten about. Since the project builds fine without them, I think
it is safe to say that they are not needed and can be safely removed.

Turning on the flag `-Wunused-packages` turns up a bunch of unused packages.
This commit removes them from `gargantext.cabal`.

(Note that `-Wunused-packages` is NOT turned on in this commit.
I tried to turn it on, but occasionally got a bunch of other warnings
which I didn't understand and couldn't get to reproduce reliably,
about packages that were supposedly added via the `-package` or `-package-id` option
(I don't know about that option) but are unused)

Some modules consist only of commented code. This removes them.

Many modules feature the `{-# OPTIONS_GHC -fno-warn-orphans #-}` pragma.
In many cases, this pragma has no effect (because there are no orphan declarations
in the module). In some other cases, a little bit of refactoring could make them
useless.

This commit removes the pragma only in those modules where removing it
changes absolutely nothing.

- edit bin/update-project-dependencies

  - sha256sum cabal.project
  - sha256sum cabal.project.freeze
- nix-shell $ ./bin/update-project-dependencies
- git add -u
- git commit

This commit maps the "Publish" action inside CodiMD/HedgeDoc to the
share URL feature.

This commit improves a bit the ShareURL internal API by wrapping the
returned URL into a proper `ShareURL` type (that internally uses a typed
representation for the URL).

Fixes #374 by not using a bespoke config file, but rather setting
the `window.domain` and `window.urlpath` via regex substitution.

This avoids using an old `window.version` that would cause the
refresh modal to popup every time after each upgrade of HedgeDoc /
CodiMD.

The new files in `docs/` explain:
1. How to get one's editor to play nice with HLS
   and the Gargantext project
2. To interact with the server/database from within GHCI

A reference to them has been added to the `README`.
