Subject: [PATCH] Fix: fnSetColumnVis was broken when used with deferred
 rendering due to the offset calculation done with the huge flat array of TD
 nodes. The fix is to simplify this somewhat and get an array for each row
 (when it is available) and process that using the optional parameter for
 _fnGetTdNodes. This doesn't result any any extra computation time, other than
 the addional time to call the function (but not to execute it), since it is
 just moving where the loop is.
