iCloud fixes

I submitted a few small fixes for Chronicle 2 last week but the update was rejected because it crashed during launch for the testers under iOS 6.0.1. I did some more research and found other developers experiencing the same problem and, from what I can tell, it's an iCloud bug. I haven't been able to reproduce it on any of my test devices and I've talked to existing users that are running just fine under iOS 5.x and 6.x.

With the App Store's busy approval queue and their looming holiday shutdown, I'm not sure I'll be able to find a workaround and get it approved until after December.
