v4.0.alpha1

• Removed front-end views from Koi so that controllers inheriting from Koi::CrudController
  will no longer render views by default, and will need views in the app itself. This makes it clear that
  developers should be making decisions for themselves as to how their content should be rendered.
• Removed default pagination from front-end controllers. If pagination is required it should be configured
  as needed.
