Title: Ditch +imb_threadSafeManager

Including my requests to adopt `NSURL`s more, this gets rid of `+[NSFileManager imb_threadSafeManager]`. Since 10.5, `NSFileManager` has been thread safe, provided you instantiate your own. It seems unnecessary to try and maintain our own cache of them as that incurs locking overhead, and file managers are pretty cheap to allocate.
