    workbench: add gb_workbench_views_foreach()
    
    This is a helper to iterate all of the GbView in the workspaces.
    I don't particularly like this, but it keeps us moving forward.
    
    I'd really like to see something in the future that manages views,
    workspaces, layouts, etc in a cleaner way.
