Anti-raid levels don't by themselves do anything, but they can be
used in overrides to activate specific automod items.
Spam detection should now be more reliable and also combine further
spam messages after the initial detection into the archive.
Messages deleted by automod no longer create the normal deletion log
entry. Instead, the AUTOMOD_ACTION log entry contains the deleted
message or an archive if there are multiple (i.e. spam).
Post date will always be more or less the time the log message is posted.
The logMessage variable in the alert action contains the full,
formatted log message that would be posted in a log channel as the
AUTOMOD_ACTION log type.
