dillard 36a30732ad Without system cron: warning and a backup that moves on while the page is open (#13); progress of the database phase; Bin tab
- The admin page and backup:status warn when background jobs do not run on a
  system cron, or the cron stopped, with a link to how to set one up.
- Without a working system cron, the open admin page moves a running backup
  forward through /api/tick, a short step per poll.
- The database phase shows the tables dumped ("db: 47/183 tables"); a backup
  that has not moved for 15 minutes says it is waiting for background jobs.
- The trash of restore points is on a tab of its own, Bin.
- New screenshots; changelog and plan for 1.0.2.
