Bump version (it was conflicted anyway)
Add Pry.auto_resize! to respond to width changes.

- Opt-in because we aren't sure where it doesn't work
- Not Coolline-aware
- Otherwise a big improvement
Adjusting ls output for voluminous output

The previous table output was geared mostly for `ls _pry_`, which isn't
a common of hierarchy. After feedback from users such as @envygeeks, we
found a few tweaks that would help the really-small layers such as those
found in Rails or in small classes, namely:

- Rolling it up onto one line, if possible
- Highlighting the heading in the colors familiar to users of GNU ls for
  "directory" style

Additionally, I took the opportunity for toning down the
private/protected method colors, because before they were green and
yellow, now they're both "muted terminal blue"

Without the ability to really get in and really distinguish colors (e.g.
using 256 colors), giving "protected" such a loud color seems wrong.
