* 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.
Moving `public/images` dir to `assets/images`, because it conflicts with gitlab CI/CD for documentation.
Moving `assets/styles.css` to `assets/styles/styles.css`.
Related to #117.
Replacing webpack by ESBuild for client code compilation (as in the
official quickstart plugin).
So we can remove deprecated webpack dependencies.
Note: webpack is still used for ConverseJS build.
This may be removed soon.
Related to issue #122.
Modal for video owner (and instance's moderators) that allows to generate a link to the chat. So you can - for example - obtain the url to use for OBS integration.
