Change default value of INTERSPERSED_ICE_THERMO

  Changed the default value of INTERSPERSED_ICE_THERMO from True to False.  All
answers are bitwise identical in test cases, because this parameter is being set
explicitly, but this does change a number of SIS_parameter_doc files, and new
reference SIS parameter documentation files have been checked in.
