Remove the identityToken KVO observer from the cloudFileSystem on dealloc
Removed an empty line.
Added 64-bit compile flags for iOS. Now compiles for 64 and 32 bit.
Added better error handling for setting up the root directory in iCloud. Seems like sometimes iCloud has a user token, but returns nil for the container URL. Now handled gracefully with error, rather than exception.
Fixed the predicate on NSMetadataQuery for newer OSes

NSMetadataUbiquitousItemDownloadingStatusDownloaded is not an attribute
on NSMetadataItem, it is rather one of the three possible string
constant values of the NSMetadataUbiquitousItemDownloadingStatusKey,
and can therefore not be compared like the now deprecated
NSMetadataUbiquitousItemIsDownloadedKey attribute which used to return
an NSNumber object containing a Boolean.
Added checks for whether iCloud is connected before any operation in the iCloud file system.
