Fix: fnReloadAjax's standing redraw was totally broken. Fixed here.

- Problem was that fnDraw( false ) was being called, on new data, which
  meant that no filtering or sorting was being applied. Need to call
  fnDraw() first, and then fnDraw( false ) to reposition the pages. Not
  ideal, but works for now.

- Worth noting that `ajax.reload()` will be a method in DT 1.10's API.
