Patch by Michael:

admin.css:

* Removed border-bottom for menu list items. The only work around to retain
the border-bottom on lists with nested items is to use divs rather than li
tags as far as I know. I think the list items are still readable this way.
* Made title of site in sidenav more differentiated from menu.
* Made color changes so that all headings are the same hue (navy bluish).
* Modified th text-align: left; for better readability. Modified
border-bottom: 1px solid #ccc; Black addded visual noise.
* Modified tr.dark background-color: #ddd, tr.light background-color: #fff;
* Changed all colors to #xxx three number hex shortcuts.
* Added hr rule to make horizontal rules have height: 1px; color: #ccc;

admin.php:

* Added 1 line to admin.php to include <link rel="stylesheet" ...>. The
stylesheet refers to a misc/print.css stylesheet which may not exist in your
misc/ directory. This fixes the flash of unstyled content that users of Win
IE 5+ are experiencing. You can use this to specify print styles if you
like. See more about this here: http://www.bluerobot.com/web/css/fouc.asp
