add `IdenticalReplyPostSameParentRule` to automod (#746)
adds a spam label to accounts that are under 24 hours doing this,
otherwise just reports. maybe too hasty on the label, can adjust. (note
our client really doesn't make it easy to make an identical post
multiple times in a row like this, where even failures will usually
close the composer anyway, so its likely to be intentional). same could
probably be applied for same author but with a maybe higher limit
