single window + has focus -> active border
single window + no focus -> inactive border
multiple window + regardless of focus -> active border
a) option set:
1) Single *visible* window in the layout - always draw a border
border color = active if os_window is focused else inactive
2) multiple visible windows in the layout - no change in existing
behavior, in particular draw_minimal_borders is respected as before.
b) option unset - no changes from present behavior
option default to false.
