Changes to make PDF output match the browser view more closely

  font-size: 18pt; instead of fount-size: 22pt;
  remove the "a" tag from def that forces font size, otherwise anchors in various contexts, e.g., headings, etc., will cause ugly rendering due to mismatched font size.
   specify font size for "pre" tags so that code listings more closely match browser rendering
