Handbook rewrite part 1: Formatting and JSON-ification!
- Everything is now defined in a JSON file - Formatting is now done dynamically and content wraps properly no matter what font is used - Added inline hyperlinks - Added a movable bookmark for quick access to a specific page - Added next section and previous section buttons to flip through entire sections at once - Added a contents button visible on every page, which navigates directly to the main contents
