/**
 * mobileUndo, a script allowing reversion of edits from
 * mobile diff pages, (Special:MobileDiff)
 *
 * Additional functionality includes changing the
 * position of the thanks button and the addition of a
 * confirm dialog to the thank button, to prevent mis-clicks
 * due to both buttons being close to each other.
 * 
 * Based on the original by User:FR30799386 at [[meta:User:FR30799386/undo.js]]
