Upgrading to Lemmy 0.19.4

Upgrading the site to Lemmy 0.19.4 so expect roughly an hour of downtime. I'll update this post right before I take the site down, and again once the site is back up.

Edit #1: OK, site will be going down now 11:31am EST. Edit #2: Site is back up - upgrade complete @ 10:46 pm EST.

A lot of things broke I didn't expect, so please let me know if you find something not work as you believe it should be and I'll see what I can do about fix it (hopefully quicker). Again, sorry about the downtime!
