Since MediaWiki 1.26, all ResourceLoader modules are loaded
asynchronously, so inline scripts now need to account for the
possibility they may be executed before the jquery and mediawiki modules
have loaded.
If you use ResourceLoader::makeInlineScript() to build the HTML script
element, your JavaScript code will be automatically wrapped in an
anonymous function and queued for execution once ResourceLoader has
started up.
