Hightlighting the down-arrow next to user name on hover

- the right-arrow wasn't highlighted on hover, which was
  inconsistent with the other header items

- changed the user-menu items highlight color from #fff to #fafafa, which is
  consistent across the header

- refactored the css to reduce specificity
