Fixed issue with iOS 7 code. Previously there was a bug where Apple was under-releasing NSDate when listing a library. To fix this, I released it. Apple has fixed this bug and my fix OVER released the NSDate.

This resolves the issue with iOS 7 and iOS 6.
Fixed issue with iOS 7.
Fixes issue with iOS 7

iOS 6 has a bug that leaks memory when listing a directory. In order to
prevent this from leaking I implemented a "hack" knowing that at some
point Apple would fix this leak.

With iOS 7 fixed that bug which now caused BR to leak OVER release
causing a crash. This fixes that issue.
