Transparent Nice Menus for both vertical and horizontal menus

I updated the code a few places, so that both vertical and horizontal menus are transparent.

Remember to put the three pieces of graphic in a folder in your theme, and to update all the paths for them to match your installation, example:

/sites/all/themes/ninesixty/images/grey50pc.png
-- rename to:
/sites/all/themes/YOUR_THEME_NAME/images/grey50pc.png

Google cache of the graphics, the original post is down.

The below based on this version:
/* $Id: nice_menus_default.css,v 1.7 2009/02/09 00:19:36 add1sun Exp $ */

It works in Firefox and Epiphany, but hasn't been tested in IE.
