(Some icons are temporary, until we get the final assets)
Also some fixes/improvements to CircularIconsPreference:
* Show the correct placeholder and +N icons.
* Fix the displayIcons-before-measure case (global layout listener was incorrect).
* Properly cancel pending image load futures (field didn't point to the actual future).
* Don't reload icons if it's the same set (depends on equals() for the items, so unfortunately doesn't work for AppEntry yet).
