* Start and stop the bot WIP
* Prosody: removing the BOSH module from the global scope (must only be present on relevant virtualhosts)
* Some refactoring
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
