Make use of icon scaling from System-mt.1102.

Note that I also added a better fast path for not having icons in lists. Yet, our tools do set the icon selector regardless of the particular preference (e.g., class icons, message icons). We would have to update #buildWith: methods to make use of that fast path *BUT* we would not get nice live updates in existing tool windows anymore when toggling icon preferences. ... which is similar to other tool-builder artifacts we get when changing the font sizes (e.g. height of button rows).
