Changeset 2915 for LMDZ5/trunk

Message:

Improved the way thermal inertia works in simulations using imposed SST and sea ice.
Removed inertie_ice which was confusing; Added inertie_sic for sea-ice and inertie_lic for
land-ice. When snow is present, inertie_sno is used instead of inertie_sol, inertie_sic or
inertie_lic. For sea-ice, added a flag called iflag_sic:
If iflag_sic=0, thermal inertia is changed over sea-ice when snow is present
If iflag_sic=1, thermal inertia is kept constant and equal to inertie_sic
