Display summary and failed tests results

I rewrite factory_Review that
* it displays status of all tests results, including sub-tests of
  run-in, etc.
* it displays detailed reason of failure; scroll by j/k.

BUG=chrome-os-partner:379
TEST=run factory test and press Ctrl-Z (switch to review directly)

Screenshot is attached to bug tracker.

Note:
The factory_ui on your machine would not be the same with
the screenshot.
