Mars GCM:
co2_ice as scatterer in radiative transfert. Need co2clouds and

activeco2ice .eqv. True. Files involved:

aeropacity_mod.F
callradite_mod.F
physiq_mod.F
updatereffrad_mod.F
suaer.F90

determine co2_ice density from temperature. Used in riceco2 computation.

Files involved:

co2cloud.F90
improvedco2clouds_mod.F90
updaterad.F90
updatereffrad_mod.F

co2condens_mod4micro.F: variable initialization
initracer.F: add nuiceco2_ref = 0.2
phyredem.F: remove co2_ice from qsurf since co2_ice => co2ice
watercloud_mod.F: tiny typo
