- Use .ab-icon:before, .ab-item:before, and #adminbarsearch:before to select all toolbar icons. - Rewrite the selector for toolbar icon hover styles so they're not overridden by default colors. - Add #adminbarsearch:before to color schemes, so its icon color is changed with the others. - Remove duplicate color rule on #adminbarsearch:before. See #25858. git-svn-id: https://develop.svn.wordpress.org/trunk@26184 602fd350-edb4-49c9-b593-d223f7449a82
