Rearrange summary bar code to consolidate Ajax and IFrame, and /home and /console

Now, Ajax will be used first, and will fall back to IFrame if JS is disabled,
and a separate page if on a text or mobile browser.
Also, /home and /console (and everywhere) now all have the same summary bar
content, which currently defaults to the original full listing.
