PEM:

• A number of corrections related to r3149 for CO2 ice management:

  'co2_ice' was not transferred to 'perennial_co2ice' at the end of the PEM run;
  In the Mars PCM, 'perennial_co2ice' is now correctly handled regarding the frost in case of CO2 sublimation/condensation.
  

• Addition of (CO2 and H2O) ice metamorphism: if the frost is above a given value, then the excess frost is transferred to the perennial ice.
• Thresholds value for ice management can now be set in the "run_PEM.def".
