Changes since 1.4: +12 -12 lines 
Yet more changes:
o adgmredi_calc_tensor
  avoiding all recomputation of gmredi_slope_limit
o adgmredi_x/y/rtransport
  added flag for excessive storing to avoid recomp. of
  u/v/rtans, dTdx/y/z
  -> this is not really necessary and very memory-consuming
o adgmredi_slope_psi:
  consistency with gmredi_slope_limit in treatment of GM_slopeSqCutoff
o gmredi_slope_limit
  re-activated full calculation of taperfct for case 'ac02'
