Title: Add pry-nav and rake console

Two minor changes I found useful in debugging things on the big file shuffle of #949:

* Adding `pry-nav` to our development group, since I'm constantly adding it in myself anyway :grinning:
* Adding a `rake console` command which loads a pry session with Shoes loaded. I found it useful in testing what was loaded by default when we `require 'shoes'`.
