The blocking-stuff button icons have been brought
closer to the power button.

The go-somewhere button icons have been moved at
the bottom.

The hostname of the current site is now shown below
the power button. The base domain is bolded.

This re-ordering is for a few reasons:

- The blocking-stuff button icons are now closer
  to the revert/persist/reload transient buttons
  which show up when modifying the blocking
  behavior of uBO.

- The makes it easier to potentially bring in a
  very basic view where only the power button and
  the statistics are shown and all the button
  icons are hidden from view.
