added some features for a restart in PLASIM in the surface_map_restart branch:
In surfmod.f90: added neworo=0/1 parameter in order to read the surface geopotential orography (also newsurf=3/4 is needed)
In landmod.f90: added three new values for newsurf:
-newsurf=3 to read glacier mask [232], orography [129] and albedo [174];
-newsurf=4 to read glacier mask [232], orography [129], albedo [174] and maximum soil water holding capacity [229];
-newsurf=5 to read maximum soil water holding capacity [229] only
