439: Dragging! Drag Everything!

Stephen just implemented a great UI feature for the 2.0 editor where all the Panels that were previously stuck to the left side of the page can now be dragged away to become an "Editor Tab" just like a file (or Block!). Now you've got a lot more freedom for what you're looking at, and of course, the editor will remember your layout should you refresh or even come back in another browser. Time Jumps
