Some tweaks to the {{int:...}} parser function:
* Respect the language given with parser options
* Replace parameters before expanding its own templates/functions, like $wgOut->addWikiMsg() does
* (bug 14404) Force content language when parsing the text to pass to LinksUpdate

* Use an anonymous user to get the parser options and the parser cache key, thus wikitext rendering is not depending of some sepcific user options such as lang, ...
* Same for the refresh link job
