// This function will add a link to your Wikipedia toolbar.  It is required both for [[User:Howcheng/quickimgdelete.js|Howcheng's image deletion script]] and my template replacement script.
// It is not the right way to do things - we should be using mw.loader, but that doesn't seem to be working right now for some reason and plugging in this old code is easier than looking up
// the new API parameters.  Please, MediaWiki developers, don't have breaking changes.

/* This code may be problematic when it comes to titles with ampersands, etc, which are stored as ''& amp ;'' in HTML (without the spaces).
  A solution that solves this is the following:
    return document.title.substr(0, document.title.lastIndexOf(' - Wikipedia, the free'));
