* build-conversejs.sh: adding the ability to use a specific commit (to
include some patches that are not upstream for now)
* Using patched ConverseJS for performance improvment (related to #96):
* debounce MUC sidebar rendering in ConverseJS (Fix#138)
* force history pruning, even if messages keep coming (Fix#140)
Hide nickname changes when previous nickname was like "Anonymous 12345".
Helps to improve performances when massive anonymous users are joining (#138), and prevent displaying unnecessary messages (#111).
* Remember the chosen nickname in sessionStorage, to avoid entering it again too often.
* Fix: if an anonymous chat user enter spaces in the nickname choice, it will allows them to keep the random nickname.
* New settings: "Ban anonymous user's IP when user is banned from a chatroom":
* if enabled, every time a streamer bans an anonymous user, it will ban its IP on the chat server,
* banned IPs are logged on disk, so server's admin can use them to feed fail2ban (for example),
* option disabled by default, because could be used to create trapped-rooms on public servers
* Start and stop the bot WIP
* Prosody: removing the BOSH module from the global scope (must only be present on relevant virtualhosts)
* Some refactoring
Links to documentation are now using the front-end language to point to the translated documentation page
(except for some links generated from the backend, in the diagnostic tool for example).
Partial fix for #224.
Bypassing Nginx for API call originated from Prosody (if Peertube >=5.1).
Can also fix some Docker setup, which needed to set the prosody-peertube-uri settings.
* Adding a help button on top of the chat, that links to the online documentation on frama.io.
* Replaced github.io documentation links by frama.io documentation.
* Adding links to the documentation in the diagnostic tool.
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
