Todd Gamblin 05c761dee9 Add package_class method to spec. ...

- Shouldn't call .package from within things like normalize() and
  concretize() beacuse spec may be inconsistent.

- Add `.package_class` property so that we can get at package metadata
  without constructing a Package with a Spec.

- should be faster than `.package` was, anyway. Use where possible.
