/**
 * Copied from [[mw:User:Alex Smotrov/edittools.js]], modified for use on the English Wikipedia.
 *
 * Configuration (to be set from [[Special:MyPage/common.js]]):
 *   window.charinsertCustom – Object. Merged into the default charinsert list. For example, setting
 *       this to { Symbols: '‽' } will add the interrobang to the end of the Symbols section.
 *   window.editToolsRecall – Boolean. Set true to create a recall switch.
 *   window.charinsertDontMove – Boolean. Set true to leave the box in its default position, rather
 *       than moving it above the edit summary.
 *   window.updateEditTools() – Function. Call after updating window.charinsertCustom to regenerate the
 *       EditTools window.
