Title: allow zero-arity proc for Controller::layout

zero-arity procs are evaluated in the context of the instance of the
controller, much like how filters work when passed blocks.

Also, Gemfile change to rack-test: https:// to git:// so people with
git not compiled with curl can bundle install properly.
