Without this, going to `https://thelounge.example.com/index.html` would return the raw file. This now excludes it from the `public` folder so it cannot be rendered as is.
Renaming the file is for good measure, to indicate that this HTML file must be templated. Because it is a straight rename with no modification, rebasing PRs on it should not be to painful, as git re-applies changes on renamed files.
Semi-working because this does not support Preview/Next. The existing image viewer is very custom to in-channel message previews and expects a certain markup, that needs rework tobe more generic.
- There is no client caching of the changelog/version anymore. Instead, server returns the expiration date of its cache, and that is used by the client as well.
- There is now a "Check now" button on the client that appears when data is stale. This means that info is fetched only once and never refreshed (it was refreshed every hour before) unless the user explicitly wants to check latest version, which in turn is as stale as server info is, i.e. 15 minutes max.
- Button style is shared with the "Join a channel" feature, `.btn-small` (not `.btn-sm` to be explicit that this is not a Bootstrap thing).
- Version checker content is now centralized in the `version_checker` template, instead of being partially in the checker template, partially in the Help template, and partially in the code.
- A "Try again" button lets user attempt to fetch info instead of forcing them to reload the page.
- Use Flexbox to display a nicer version checker: icon is slightly bigger, and button is always aligned on the right.
- Changelog logic has been removed from `lounge.js` and moved into the component file.
- Changelog template is only passed what it needs instead of everything the server gives us.
- Public version now displays version checker, since server is caching things.
- Cleaner code overall.
This commit packs 2 fixes:
- Reloading the page while viewing the settings or help window would now send you to a channel window. This was broken when fixing an issue with the "Join a channel..." form
- Reloading the page while viewing the changelog would also send you to a channel window. This is because, on reload, the click emitted was restricted to sidebar and footer, while it had to be emitted from the help page. It is yet another aspect of our wonky window management and hopefully we can make this much more robust with a better overall solution.
Without this, `target` was matching all of the lobby link, the "Join a channel..." button, and the join form submit button. This change restricts to the first one.
