templates: Make stilistic changes in dashboard

- Remove a table with redundant info; it was displaying server's stats,
  which was already in another table
- Add last update info at the top of the page
- Make page more robust by checking if ogLive images are available.

Before this patch, page shows a traceback if the ogLive list are not available.
