Spliting render responsibilities into two methods

I want to render the primary content and the related content.
Removing spec dummy; This will be auto generated
Explicitly adding to loadpath

When running a feature, and using the dummy app, I want the load paths
to include the gem's lib. This way we don't have a nested Gemfile and
all kinds of confusions.
Adding capybara and sqlite for testing purposes

The dummy application is going to use sqlite instead of ActiveFedora
as that is an extreme path of pain.
Removing controller check for missing template
Tweaking Rakefile to be more usable
Removing nested rake tasks
Reworking presenter rendering to use delegation

Instead of rendering partials, I'm asking the presenters to be
responsible for rendering their requisite parts.
