Code Issues Releases Activity

Tidy up use of typeof and undefined in DataTables - the main goal is to reduce code size under 70K here, but its a good opertunity to get this area sorted out. Note that the unit test update for fnInitComplete is because 'json' is now always passed through, although it will be undefined in anything but Ajax sourced client-side processing.
