Fix: Initialisating multiple DataTables with a single call was broken

- Because of the manipulation of the initalisation object initialisation
  of multiple tables with a single jQuery call (i.e.
  `$('.dataTable').dataTable();`) was broken since the second table
  would see the modified init object. Need to take a coopy of the object
  before entering that state.

- This could probably do with a bit of a clean up sometime...
