This adds support for syncing ownership on Unixes and on Windows. The scanner always picks up ownership information, but it is not applied unless the new folder option "Sync Ownership" is set. Ownership data is stored in a new FileInfo field called "platform data". This is intended to hold further platform-specific data in the future (specifically, extended attributes), which is why the whole design is a bit overkill for just ownership.
