Added a new runtime flag, LAYER_Z_INIT_IC_EXTRAP_BUG, to allow for the
correction of a vertical indexing bug when initializing a layer-mode
configuration from a Z-space temperature and salinity file with nominally
unstable density profiles in the bottommost points in the z-space file. Also
corrected some spelling errors in MOM_state_initialization.F90. By default, all
solutions are bitwise identical, but there is a new entry in some
MOM_parameter_doc files.

I assume this would have affected CM2G63L initial conditions? Might explain that initial bottom warming Toni asked us about...
