System Updates

I got bored and rather than do thesis work, I decided to work on my page layout.  The primary change is in the main index stylesheet, however it brings in some new compatability issues.

Where my previous layout worked in all browsers, but looked ugly in Internet Explorer (due to the latter's borked CSS2 support), the current layout makes extensive use of PNGs, due to their alpha-blending and transparency options.  In other words:  this site will look just plain ugly in IE.  Of course, being the gentleman that I am, I am offering IE users a choice:  you can either deal with the ugliness, or you can install a standards compliant browser.  (Think of it as the Internet era equivalent of an "Evolve or die!" ultimatum.)
