0.2 pull request - Add ability to break by Word Count instead of just
specifying page count
Version 0.2: paging by word

Build on work by @bendoh merged in f96afe5397 and implement two paging options as toggles in the UI. Also makes the approach to applying the various paging types more modular and a bit easier to follow.

Lastly, WP coding standards. There's lots to clean up, so I only dealt with those bits I actually touched in the aforementioned work.
Minor cleanup leftover from 42297f7.
