Message:

Minor change to internal parameters of the thermal: smoothed detrainment profiles, reduced the contribution of upward subsidence to entrainment drag, and increased pressure torque induced drag. Consequences : more precise prediction of zmax (it was overestimated by 5 to 10 percent during the late afternoon), no consequence on the thermal structure, better predictions for internal variables (much better w profile and detrainment rate profile). Tested on both high resolution and low resolution (33 level grid from me and 36 level grid from Forget)
