refactor(grid): implement rightleftcmd as a post-processing step

Browse Source 
Previously, 'rightleftcmd' was implemented by having all code which
would affect msg_col or output screen cells be conditional on `cmdmsg_rl`.
This change removes all that and instead implements rightleft as a
mirroring post-processing step.
