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
Related to https://github.com/JohnXLivingston/peertube-plugin-livechat/issues/117
* the front-end now use global constants, based on the translation key
* build-client.js use the ESBuild "define" directive to replace these
globals at compile time, by the english value
* build:client must now be called after build:languages
* moving the loadLoc and loc backend functions in a separate lib
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`.
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.
* new option to allow external xmpp account s2s connections
* settings to setup the port and network interfaces
* documentation WIP
