Move to project based directory structure

Update generators to abide by the following directory structure:

• Foo (named after production name)
  • production (root of limelight files)
    • default_scene (or named scene)
    • production.rb
    • styles.rb
  • spec
  • features
  • Rakefile (what rake tasks should be provided by default?)

(Am I forgetting something?)

Will the pack command also have to be updated?
