Photo Statistic

This update introduces device comparison, a new tool to repair a stuck iCloud Photos sync: two devices signed into the same iCloud account find each other over the local network and compare their libraries in a step-by-step wizard, drilling down year by year, month by month and day by day until it is clear which photos and videos are missing where; both devices then place the missing items into the app's album so iCloud picks them up and carries them across. A second new view folds every year onto one calendar, so January holds all your Januaries and 24 December every Christmas Eve, with the usual drill-down from months to days to hours down to the pictures themselves. Starting out is simpler as well: a welcome screen explains why the app needs access to the photo library, the analysis then starts by itself, and the numbers of the last run are kept on disk so the year list appears right away while the library is counted again behind it. The buttons above the year list now adapt to the width of the window and fold into a "..." menu when the row gets too narrow.
