add boundary call to scale_omega

[jcwarner]

Can we add a boundary call in scale_omega so that the output of omega is consistent during periodic simulations? When used now, the variable omega is never filled on the outer rho points (since it is not used during computations). But for output purposes, especailly periodic simulations, it would be nice to see omega be uniform in the along-periodic direction, instead of having zeros along that boundary. This can be accomplished by adding to scale_omega: 1)

USE bc_3d_mod, ONLY : bc_w3d_tile

2)

! ! Set lateral boundary conditions. !

CALL bc_w3d_tile (ng, tile, &

& LBi, UBi, LBj, UBj, 0, N(ng), & & Wscl)
