Log bugs found in glimmer-cism /parallel version

 * eismint-1 (e1-fm.1)test gave basal temp of ~-3oC at the divide instead of ~-11oC. In glide_temp.F90 gridwvel, wvelintg, chckwvel use velocity%uvel/vvel instead of velocity_hom%uvel/vvel


 * eismint-1 (e1-mm.2 & e1-mm.2) temp at ocean -ice boundary set to airtemp. Thickness=0 and velocity=0 but temp=airtemp for all levels
