Play Slick compile time dependency injection sample

I spent some time trying to create an project using playframework 2.4 and play-slick module with compile time DI.

So I translated the play-slick di sample to use compile time di.

The sample features:

• Evolutions by mixing with SlickComponents with SlickEvolutionsComponents with EvolutionsComponents into ApplicationComponents and initializing evolutions when the app starts.

class ApplicationComponents(context: Context) extends BuiltInComponentsFromContext(context)
  with SlickComponents with SlickEvolutionsComponents with EvolutionsComponents {
...
  // This is required by EvolutionsComponents
  lazy val dynamicEvolutions: DynamicEvolutions = new DynamicEvolutions

  def onStart() = {
    // applicationEvolutions is a val and requires evaluation
    applicationEvolutions
  }

  onStart()
}

• In memory database configuration for tests
• Access to your your app components from tests by using a specs2 scope:

  "CatDAO" should {
    "work as expected" in new WithApplicationComponents {
      val dao: CatDAO = appComponents.catDao
      ..
    }
  }

I did a pull-request to play-slick project, but it's still to be merged.
