Re-design word handling, add e, E, W, B, etc.

* Add functions for moving to the beginning/end of words (vi `b', `e').
* As it turns out, there are many possible interpretations of what a
  word is. Now we have a function for each reasonable interpretation,
  and the default settings match those of vi (and w3m in w3m.toml).
  (Exception: it's still broken on line boundaries... TODO)
* Remove `bounds` from lineedit, it was horrible API design and mostly
  useless. In the future, an API similar to what pager now has could
  be added.
* Update docs, and fix some spacing issues with symbols in the tables.
