 * Admin highlighter 3.0
 * ---------------------
 * Derivative of of User:Theopolisme/Scripts/adminhighlighter.js
 * Changes: cache list of admins, and tweak css to use nicer one by Jorm.
 * This script highlights links to admins' userpages or talkpages in bodyContent
 * (that is, everything but the tabs, personal links at the top of the screen and sidebar)
 * by giving them a light background and border.
