* Use the new `expect().to` syntax
* Avoid general fixtures by minimizing usage of `let` and `subject`
* Define as few support classes as possible, and use them for name
lookup only - all behavior is introduced by stubbing
Lots of changes here:
* rake draper:install no longer needed
* don't generate an ApplicationGenerator by default
** If one exists, the generator respects it
* Fixes#53
