book theme bugfix for list causing page weirdness

I previously posted My book theme and discovered that on some pages, the side-scrolling was not working correctly. This fix is (hopefully) temporary, as it eliminates list-styling features. But it seems to work, and was the quickest thing I could come up with. Follow my #bearblog posts for any additional updates. TLDR, add this to your theme: li { display: block; }
