diff function

[tregmos]

NPBackup-gui: It would be nice if one could make the differences between two snapshots visible. For example, when selecting two snapshots and doing a right-click on one of the selectes snapshots, there could be a choice "show differences". As restic has a diff command, I think this wouldn´t be very difficoult to implement.

Seems like a good idea.
Will consider, but a ui rewrite is currently being considered, so that will probably wait until next UI is ready.
