site updates

I just went through the site and fixed all the possible dead links, pictures, spreadsheets, etc. I could find, so the site is back to a useful state. It's entirely possible I missed stuff, so if you see anything broken, PLEASE LET ME KNOW.

I'll probably work on modifying the template, as the narrow column display is good for cheerleaders posting about their feelings, but not exactly fitting for all the graphs, charts, histograms and other crap tuning requires. So if the site looks goofy this weekend, just have patience and keep checking back.
