Listology Engine Updates

I've made more boring no-new-enduser-features changes to the Listology engine. Let me know if you notice anything weird. The big thing to watch for is login weirdness, as I have now completely decoupled Listology logins from QuoteHog logins. Your Listology ID will not work at QuoteHog (although you can create a duplicate login over there if you like). Everyone that has posted comments to QuoteHog already has had their accounts duplicated, but I cleared out all preferences (e-mail address, notifications, etc.). You can update those yourself as you see fit. Thanks!
