 *  Description: For pages that have something like Template:Wrongtitle, replace
 *               the title, but only if it is cut-and-pasteable as a valid
 *               wikilink. For instance, "NZR WB class" can be changed to
 *               "NZR W<sup>B</sup> class", but [[C#]] is not an equivalent wikilink,
 *               so [[C Sharp]] doesn't have its main title changed.
 *
 *               The function looks for a banner like this: 
 *               <div id="RealTitleBanner"> ... <span id="RealTitle">title</span> ... </div>
 *               An element with id=DisableRealTitle disables the function.
