* Implement torrent nuking ability for mods
This deletes all torrents of a specific user.
A current caveat is that it will delete both sukebei and nyaa torrents,
but will only leave a log entry in the current flavour's log.
Also did some bootstrap untangling on the user view page.
* Per-flavour logging
Hopefully this works. Maybe.
* Tracker API: chunk into 100-element sublists
* isort
* Restrict nuking to superadmins
Also do a lint.sh.
Added migration script!: remove sukebei_ lines if your local db does not have those.
Show users ip address on user page for superadmins.
Rename Admin to Moderator internally.
Moderators can now change user level to trusted.
Superadmins can make users moderator.
Improve changing user level.
