Support background syncing using push notifications

Prior to this commit, iCloud syncing would only happen while the app was
open and had focus. This commit uses CloudKit silent pushes. However, it
is noted that this API is broken in the 26.4 versions of Apple's OSs and
so this will not change behaviour for users on those versions.
