New: Language callback function for the information element. This can be used to customise the language shown in the information element beyond what is possible with the built in language string options (for example plurals). The arguments are fnInfoCallback( oSettings, iStart, iEnd, iMax /*no filter*/, iTotal /*after filter*/, sOut /*DT rendered string*/ ) - 2520
