Faster work pages

Thanks to Chris, LibraryThing is slowly identifying and overcoming its database problems. A recent change gave us greater stability and reduced "skews" between servers--a source of much hair-pulling.

Although faster overall, some pages got dramatically slower, including the "works" pages. Commonly held works, like the Da Vinci Code, could take 15 or even 30 seconds to load. I solved that problem so that even the "worse" pages now load in 2-4 seconds, given a fast connection.

I imagine some of you just stopped clicking on works pages. It's safe now!
