Fh-fablib

~~~~~~~~~~~~~~~

- Fixed ``nine-disable`` to backup and drop the database for real.
- Promoted ``_reset_passwords`` to ``reset-pw``.
- Removed the explicit activation of pip's 2020 resolver from pip
invocations, it is the default now.
- Added ``nine-restart`` to restart the application server.
- Started executing nodejs binaries using ``npx``.
- Avoided pip 20.3.2 because it downloads too many packages.
- Added a ``--fast`` switch to ``deploy`` which skips Webpack.

~~~~~~~~~~~~~~~

- Allowed setting the ``environments`` config key to produce nicer error
messages when forgetting to set an environment with which to interact.

~~~~~~~~~~~~~~~

- Started using pip's 2020 resolver when upgrading the virtualenv.
- Started terminating deploys when there are uncommitted changes on
the server.

~~~~~~~~~~~~~~~

- Started sourcing ``.profile`` again when running psql admin commands
on the server.
- Fixed many problems with obviously untested ``nine-*`` tasks.

~~~~~~~~~~~~~~~

- Added ``github`` to create a repo on GitHub using the `GitHub CLI
<https://cli.github.com/>__` and immediately push the code there.
- Fixed uses of ``input()`` which somehow didn't work like they were
supposed to at all.

~~~~~~~~~~~~~~~

- Renamed the entrypoint from ``fab`` to ``fl``.
- Switched from running ``pip`` directly to the recommended ``python -m
pip`` everywhere.
- Avoided starting too many processes by executing binaries in
``node_modules/.bin`` directly instead of going through ``yarn run``.
