- global auth should now be able to see chat logs of rooms they can't
moderate
- secret and personal rooms that a staff member is either currently in,
or has auth in, will now show up in the main logs list (although
you should just use /chatlog, it's much easier)
`user.can` and `user.authAtLeast` now take `Room | BasicChatRoom`
instead of `BasicChatRoom`. It's now significantly less necessary to
cast things to `BasicChatRoom`.
