Speedups redux

We had load averages going back up over 2.5 again, and made some changes which dropped them back down to around 0.6 again. I turned on a setting which makes it easier for browsers to cache images and css and javascript files; went through the two javascript files that make up the menus and combined them into a single file (which I will minify later, after going through an extended revision); and moved the “stolen.gif” image which is shown to people trying to show our graphics elsewhere (without permission) to Amazon Web Services temporarily (while we see what it costs to keep it there). If the latter is successful, we will move some other popular files there, because it speeds things up (among other things, AWS puts them closer to users outside the Michigan area).

So things should be faster as I run the Red Queen’s Race.
