Title: Replace UKDirectoryEnumerator by NSDirectoryEnumerator

See https://groups.google.com/forum/?fromgroups#!topic/quicksilver---development/P7C4vYoDLc8 for the discussion

NSDirManager is still slow than the UK counterpart, but UK... is causing crashes and is using deprecated methods, so best to avoid it.
