Automatically refresh wallpapers

If there's a network error schedule retries every 10 minutes, and afterwards abort and show the error message.
For successful retries, schedule a refresh every six hours; if there's a network error, don't notify, and see above. Otherwise remember the last successful refresh in settings.
Refresh also when the extension is enabled, or the network connection established, but only if the last refresh is more than six hours ago.
