Fix: Album description showing up in Photos when photo has no synopsis
fix: Photo now shows correct confirmation screen
fix: Photo now gets auto-committed according to Gallery approval workflow
fix: Formatting problems in Album view
fix: Photo and Album assets now retain their Owner after other users edit them.
fix: Gallery::Utility migration now retains createdBy, creationDate, and ownerUserId.
Testing Gallery::Utility a bit more thoroughly.
fix: Photo EXIF data now gets cached correctly and sanitized for references (since JSON won't store them and they're of no use to us anyway).
