Restores original GetLanguage code and adds fromCache bool parameter to indicate whether or not the ILanguage returned should come from cache or be re-calculated. fromCache is true by default. this ensures previous GetLanguage functionality works, and also fixes the situation where you are calling GetLanguage on multiple items which could have different languages in the same HttpContext.
