Since we no longer show the noisy git updates to the user, it has become
harder for them to know whether a sync to the cloud was successful.
Since a manual sync will never show the new 'what did you change and
here's how you undo it' notification, it seems easy enough to simply
show a status update.
This adds a passive notification with no action button after the user
either uses the main menu or pulling down on the dive list in order to
trigger a manual sync.
