* Fullscreen chat: now uses a custom page (in other words: when opening the chat in a new tab, you will have the Peertube menu). WIP
* some code refactoring (getBaseRoute moved to util/uri, ...)
* 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.
* 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.
* 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
