Parameters:
 * 1=wikicode for the language and name of the CSS formating class (mandatory)
 * 2=description text (optional, default is empty)
 * 3=title for tooltip (optional, default is empty)
 * name=alternative parameter name for parameter 3
 * 4=standard code for lang tag in HTML (optional, default is same as parameter 1)
 * 5=extension text shown after the language name before colon (optional, default is empty)
