app4, back online

[Mike McGrath]

I had been waiting for the transifex deps before bringing app4 back online
but decided not to wait any longer.  pkgdb, smolt and mirrormanager are
all running from this box.  My hope is this additional capacity will help
quell the nagios alerts we've been getting over the last couple of days
with the ultimate goal of getting the next smolt version out (which has
some more efficient sql in it.... Its monthly checkin time.
