Prototype/experimentation:

* Context-specific headers

* Killed tabs bar (incomplete, need some service pane work to communicate the full effect)

* High contrast for important elements, low contrast for less important elements

* Revisited shuttle controls layout

* Preliminary pass at status display

* Includes an alternate layout where the shuttle controls are at the bottom of the window

Broken:

* Most of the element ids are different so many overlays wont work = broken add-ons

* Faceplate jiggles when the length of the text displayed changes

* Opening links in new tabs confuses the browser

* No mini player for now

* Quality on non-Mac platforms is unknown

* I reused the exact service pane node icons from sidecar

* A lot of bugs that result in ugliness

Feedback welcome, please.
