Always Show the Statusbar

Keeps the status bar visible but hides the statusbar panes when a non-editor is focused.

Yes, however, it's dangerous because `show()` will add an inline style that wasn't there before:

```javascript
$("#working-set-list-second-pane")
[<div id=​"working-set-list-second-pane" class>​…​</div>​]
("#working-set-list-second-pane").hide()
[<div id=​"working-set-list-second-pane" class style=​"display:​ none;​">​…​</div>​]
$("#working-set-list-second-pane").show()
[<div id=​"working-set-list-second-pane" class style=​"display:​ block;​">​…​</div>​]
```

This would trump any class styles applied to the element.
