books can be added

- debug function added
- updating progress added
- book select/add multifunction (ew sounds like corpo-speak)
- fixed initial priority assignment to be randomized
- pulled out preset function
- normal exit capability (lol)

 - [x] Store progress as a numerical value? (Unread = 0, read = 1, in-progress in-between? Too easy to forget how it works?)
 - [x] Store pages as an option,
   - [ ] allow a weighted priority based on remaining percentage or whatever.
 - [x] Store items as an array instead of object, because that makes the JSON output more consistent -> smaller JSON commit differences.
