Documentation translation using weblate.
* Use po4a to generate .po files from the english markdowns, then to generate translated files
* Some pages can be marked as «english only» (for technical documentation for example)
* New Hugo shortcode to use application strings in documentation (for example for settings names)
* The code of conduct is no more translated, but there is a link to official Contributor Covenant translations
* Adding all plugin's supported languages

To make the Weblate integration simplier, this commit merge all
translations in yml files (there is no more distinction between
standards and settings strings)
This yml files will be handled by Weblate.
TODO: document the new translation process.
Letsencrypt certificate import procedure was not working on server that had never installed Prosody.
Adding `prosody_user` in the Prosody configuration file to fix this.
Updating the procedure: the `chown` is no more needed in `/etc/letsencrypt/renewal-hooks/deploy/prosody.sh`.
Trying to connect to a remote instance using direct s2s won't work if local instance has not the feature enabled, and if the remote instance does not know the local one.
So using Websocket S2S in such case (that embed a discovery mecanism).
This commit is a dirty hack to fix issue with ARM64 Prosody AppImage.
The fixed appimagebuild tool is not released by the dev team.
So i patch it in my build script. This is not a good solution, but it
works, and let me go forward.
Note: websocket s2s is not working yet, still WIP.
New Features
* Chat Federation:
* You can now connect to a remote chat with your local account.
* This remote connection is done using a custom implementation of [XEP-0468: WebSocket S2S](https://xmpp.org/extensions/xep-0468.html), using some specific discovering method (so that it will work without any DNS configuration).
Minor changes and fixes
* Possibility to debug Prosody in development environments.
* Using process.spawn instead of process.exec to launch Prosody (safer, and more optimal).
* Prosody AppImage: fix path mapping: we only map necessary /etc/ subdir, so that the AppImage can access to /etc/resolv.conf, /etc/hosts, ...
* Prosody AppImage: hidden debug mode to disable lua-unbound, that seems broken in some docker dev environments.
* if both local and remote instance have external XMPP connections enabled, the user joins the remote room with his local account
* some code refactoring (builtin.ts)
Note: documentation and settings descriptions are to do.
Related to #112
* new option to allow external xmpp account s2s connections
* settings to setup the port and network interfaces
* documentation WIP
