Added functionality to set up public grid functions (sbp_dx, sbp_dy, sbp_dz)

containing the delta's used in the Kreiss-Oliger type dissipation. This is
activated with a parameter (use_variable_deltas) and a routine
(SBP_DeltaInitial) is scheduled at BASEGRID to set the default values
initially. The grid functions can be modified later by a scheduled user
function if so desired.
