Winterwx (NOAA-EMC#614)

* Six new winter wx diags added to output, accumulated fields added to restart file and changed nsradar_reset, radar_reset to something that makes more sense, that is, nsfullradar_diag and fullradar_diag. Also, added new namelist parameter to use new precip ice density with the NOAH LSM. Code changes to upp also made to include the new winter wx diags.
