Message:

fix #21208, fix #21207 - center icons and align text in preference and preset lists

Use padded icons for tagging preset icons and for list entry/label icons in the preset dialog, so non-square icons are centered and the texts line up. List entries without an icon get a blank one if other entries of the list have an icon.
