I did this so we have `this.document.file.fullPath`.

Yes, I had to rework the code in `EditorStatusBar`. One implication (of the new preferences changes in general, and not this change in particular) is that the status bar now updates for the focused editor. So, if you happen to have different prefs for .html and .css files, then when you switch focus between main and inline css editor, the prefs in status bar with change for the current file being edited. Or should status bar always show prefs for main editor?
