Closed a minor XSS security vulnerability in the theme_links() function (SA-2008-044 http://drupal.org/node/280571)

clear: both for div.meta. made space for openID logo. moved tabs to the top of the page. cleaned up tabs by styling them. Fixed footer padding so that it doesn't show the background.

Changed breadcrumb divider, removed last CC icon, added forum stylings and icons, conditional category display for forums, code and cite tag stylings, added book icons (add page, print, etc), added UL style for proper stylings on right sidebar, stylings for form submit buttons, changed info description, footer can have more than 3 blocks.

#213605: pager top margin fix.
