Minor updates

I just did the excellent Ardent Atheist podcast tonight. Since there'll be a link back from there to my site, I thought it was time to make some quick changes/improvements to the site, one of which was a simple cleanup of the theme. The old one was slow to load and overstyled. This one I picked in a hurry, but it's clean and easy to customize and will probably change over time. It's still an improvement, though. I hope you appreciate the amount of effort I go through for you at 2AM on a work night.
