 Kranc generated thorns now have support for optimisation through
 vectorisation. They just need the option UseVectors -> True to be set when
 creating the thorn. The attached patches enable this for the BSSN thorns
 in McLachlan.

 I have tested that this gives a significant performance increase (close to
 2x in the right-hand-sides in the cases I tried) and also that it agrees
 to within what would be expected given roundoff differences with the
 results of a BBH simulation with vectorisation disabled. Additionally, the
 testsuites still pass with this patch applied.
