Fix extra highlighting issue

When the attr of a row is set to A_STANDOUT, it sometimes
makes the surrounding border stand out as well. This removes
that attribute and now the row is just colorized white with
an indication arrow in front.
Fix original menu selection styling

The extra highlighting issue was occuring because the attribute was
not getting set back to Ncurses::A_NORMAL after the row. This caused
Ncurses::A_STANDOUT to get applied when the border was created.
