CSCI E-168

While working on the page that will display Ruby style suggestions, I discovered that the 800 width was really not too hot for code snippets.

So I have hacked the theme to assume that the screen is 1024 pixels wide or larger. Even if you are in that 14% (probably less now) of users with an 800-pixel wide screen, the main page area still fits within that width.

There are still a couple of widths that are funky (e.g., for comments) and I had to lose (for now) the banner image and the background behind the sidebar, but those will come back in some form.
