Done. This feature is added to the CVS. To use it, pass the parameter "lang" in the URL using a valid language name - any in
WEB-INF/config/languages/locales.properties.
In order to have this functionality working correcly,
you should not use "Friendly URLs". Example:
There is no need to persist the language through other pages, it is done internally by jforum. Also, it is only possible to change the language using request parameter for Anoymous users and in the forum listing page.
