This is non-trivial, the `UserBBCode` is not being executed for `text/plain` outputs (or rather: no BBCodes are executed for `text/plain`) outputs.

> Fix fa-flash icon, which is now animated (e.g. located in the notification settings for instant notification). This was fixed upstream. The `fa-flash` animation was renamed `fa-beat-fade` in Beta 3.

Moving this to 5.5. because the automated marking of notifications as read should be cleaned up first.
