cGH.h: Add three new fields cctk_timefac, cctk_levoff, and

cctk_levoffdenom to the cGH structure that simplify handling
coordinates in mesh refinement settings.

cctk.h: Pass the new fields to Fortran routines.  Add a new macro
CCTK_ORIGIN_SPACE to simplify using these fields.

CactusDefaultComm.c: Initialise the new fields.
