Subject: [PATCH] Reenable cron and packages blocked by it

I'm not familiar with yesod-job-queue but if the comment is correct, reenabling cron means it can also come back. I went ahead and purged derive from cron, opting instead for generics-sop. According to travis, my build should be working for nightlies and recent lts.
