Lemmy 0.18.4 Update

I noticed some timeouts and DB lag when I logged in early this afternoon, so I have gone ahead and updated the instance to 0.18.4 to hopefully help clear this up.

We also have a status page available at https://overwatch.nulltheinter.net/status-page/946fd7fd-3ae3-4214-bbbf-dd7206566104 and will soon have this working on status.lemmy.tf.
