Title: Scene should provide the Box2D world if physics is enabled, fixes #40

Scene now provides World automatically without needing to add a
World container around all entities and bodies.

Added a property to Scene for "physics", if set to true the
scene should create a World.

World and Body are now uncreatable types.
