Spamer script, desktop file and symlink for autostart.

I'm using ElementaryOS which has Python 3.6 as the system Python3.
It's a supported Python version, the system packages will be used and
everything that runs on that version will run on later versions.

Like before, Nextcloud!

The domain was changed to endlessos.org.

Again, for syncing with Nextcloud.

For sending my accountant.

Again, Nextcloud adaptations.

There's no code I worked on there, it's like the node_modules directory.
Move it under .local so it's not copied by Nextcloud.

You guessed it, Nextcloud!

Again, Nextcloud.

Nextcloud will back it up!

Google SDK CLI profiles for Shore and Endless.

Whem the database for clipped gets corrupted, it needs to be deleted and
the application restarted. Script that.

- More scripty (set -eu, not just an alias in a script).
- Update appstream data.

Git script to remove temp work tress and prune work trees.

So there's a different default private key and also separate the public
keys I use to encrypt for other people in Endless.

The prune_ssh_sockets shell function would always delete the
ControlMaster sockets (the open file handlers would have a random suffix
and the check would always show that the socket wasn't open by any
process). Instead add a prefix to the ControlMaster sockets and ignore
them when pruning. Those sockets are always deleted when the process
exists. Also, mark the vim filetype for the ssh config fragments as
sshconfig.

Don't delete sockets that are still in use (have an open ssh client
listening).

So now I can run `$(eval docker remote hostname)`.

- Add toolbox script, bash completion.
- Better ansible-local in Makefile (match shell alias).
- Delete gcloud SDK bash completion, the mirror in github is gone.
- Update to newer version of binaries and vendored files.

In some cases (like a chroots or containers with minimal /dev)
/dev/stderr is not available. Replace outputting to fd 2 instead.

git grep -l '>> /dev/stderr' | xargs sed -i 's@>> /dev/stderr@>\&2@g'

Otherwise the files (as root) are written to my home directory and when
I correct the ownership I get this error: "Refusing to operate on a user
installation as root".

- Add missing symlink to the wrapper script, without it the scripts
can't be called as Vagrant commands.
- Fix pylint issues.

Too many changes in one commit that aren't relevant to each other all
because I didn't commit these for some time and they piled up, exactly
what I shouldn't do.

- Remove some Git submodules. They're not needed.
- Remove the REPREPRO_BASE_DIR environment variable, it's set with
direnv inside that project.
- Use Docker Buildkit.
- Use auto Python interpeter with Ansible, prefer Python3.
- Better ls aliases.
- Netcat aliases to listen and check ports and sockets.
- Aliases and functions for Terraform.
- Use Black to format Python code.
- Show the run duration and exit code in a line before the prompt, maybe
better with Bash earlier than 5.0, where there's an annoying with line
wrapping.
- Valid name for the flatpak_kill shell function.
- Delete user-dirs files, didn't do anything anyway.
- Convert README from reStructuredText to Markdown.
- Don't install gsutil with Python2, use snap to install the Google SDK.
- More pre-commit hooks, update the exiting ones, format the file for
yamllint, Use flake8 from it's repo, the one from the hooks repo is
deprecated.
- Clean the Shore SSH config.
- Add the shared AWS keys to the Endless SSH config.

Add dt (delayed tee), like tee but can output to the file that's being read from (for example sort foo.txt | dt foo.txt).
