This adds a special filter to topic lists that will filter to tracked and
watched categories.
To use it you can visit:
`https://sitename/?filter=tracked`
`https://sitename/unread?filter=tracked`
and so on
Note, we do not include explicitly tracked and watched topics **outside** of
the tracked categories and tags.
We can consider a `filter=all_tracked` to cover this edge case.
Before this commit if you were bulk removing group members and passed in
a user who wasn't currently a member of that group the whole request
would fail. This change will return a 200 response now listing the users
that were removed and those that were skipped.
Since `Discourse.SiteSettings` is removed, helpers can now include and
call `helperContext().siteSettings` to get access to the settings
without using a global variable.
To reproduce the initial issue here:
1. A user makes a post, which discourse-akismet marks as spam (I cheated and called `DiscourseAkismet::PostsBouncer.new.send(:mark_as_spam, post)` for this)
2. The post lands in the review queue
3. The category the topic is in has a `reviewable_by_group_id`
4. A user in that group goes and looks at the Review queue, decides the post is not spam, and clicks Not Spam
5. Weird stuff happens because the `PostDestroyer#recover` method didn't handle this (the user who clicked Not Spam was not the owner of the post and was not a staff member, so the post didn't get un-destroyed and post counts didn't get updated)
Now users who belong to a group who can review a category now have the ability to recover/delete posts fully.
This fixes an issue where sometimes when composing a post and uploading a video/audio file, _loadCachedShortUrls/the uploads controller would return a full URL with origin, instead of just the URL with the host e.g. http://localhost:3000/some/video.mp4 instead of just //localhost:3000/some/video.mp4. We were prepending window.location.origin onto the URL no matter what, and since http://localhost:3000/some/video.mp4 does not match the host URL regex, we were ending up with something like http://localhost:3000http://localhost:3000/some/video.mp4 which broke composer previews. This was only noticed with a video upload in a secure upload environment.
Previously we considered 'upload rows without etags' to be exempt from the check. This is bad, because older/migrated sites might not have etags on all their uploads. We should consider rows without etags to be broken, since we can't check them against the inventory.
This also removes the `by_users` scope. We need all uploads to be working, even ones created by the system user.
