WIP: Fedora 4 with AT 0.4.0 [Do Not Merge]

:warning: 
@jcoyne @no-reply This is where things stand currently with getting AT 0.4.0 running in ActiveFedora with Fedora4.  There are over 500 failures right now, so it's certainly breaking a lot more in the fedora-4 branch than it's fixing.  This'll need more work before it's merge, I think.
