Changes since 1.3: +35 -3 lines 
fix Stevens BCs by using intermediate velocities of previous
time step as "baroclinic" contribution rather velocity of one grid cell
inside the boundaries; more consistent but makes the entire treatment
more complicated, requires new pickup files and two new S/Rs:
obcs_copy_uv_n and obcs_save_uv_n
keep old version with flag OBCS_STEVENS_USE_INTERIOR_VELOCITY
(undefined by default)
