Changes since 1.5: +1 -17 lines 
Minor changes in pkg/ggl90:
 o GGL90diffKrS was removed --> always use GGL90diffKr
 o GGL90viscAr was removed --> replaced with GGL90viscArU, GGL90viscArV
 o hack of mxlMaxFlag=2 --> ensure mixing between first and second level (commented out for now)
 o change in max/min operations to ensure that smoothing is ok
 o smoothing of GGL90viscAr was moved to ggl90_calc.F (as done for GGL90diffKr)
 o always use diffKrNrT as background profile (i.e. never use diffKr field)
