Make menu underlines and menu hovers match styles

[nicolepaschen]

It's common to have the active menu item underlined. Currently I can add a bottom border to the menu item to give it an underline, but the alignment is off - it's not centered under the text. Also when I use an Underline hover effect, the underline doesn't line up with the border:

Please make the bottom border centered on the text and have it be the same distance away from the text as the underline hover effect.
