feat(scrolling): add commands and config for the scrolling layout

Focus, move, resize, retile and closing a window now go through the strip of
columns in the Scrolling layout. New commands: consume, expel,
toggle-column-stack, scrolling-layout-full-width and center-focus. A top
level scrolling section configures centering, centring a lone column, and
the minimum height of a window in a column of several.
