 Running qc0_mclachlan.par from the par directory of a 2016_05 checkout I
 get:
 {{{
 WARNING level 1 from host 127.0.0.1 process 0
   while executing schedule bin CCTK_PARAMCHECK, routine
 ML_BSSN_Helper::ML_BSSN_ParamCheck
   in thorn ML_BSSN_Helper, file
 configs/sim/build/ML_BSSN_Helper/Parameters.c:157:
   -> Parameter ML_BSSN::my_initial_boundary_condition is outdated; please
 update the parameter file. Do not use this parameter, and set up initial
 boundary conditions as usual.
 }}}

 Since qc0_machlan.par is a typical "beginner's file" and our tutorial
 mentions it, we should update so that it does not produce warnings when
 run anymore. We should also I believe update the paramwarn message to be
 more helpful since likely the user did not know what the "usual way to set
 up initial boundary conditions" is, otherwise they'd have done so :-).

 Major as this should be be fixed for the next release.
