Revert "test(angular): Track referenced but not exported symbols"

This reverts commit 7bc327492c7993f7eb25e792ba16367653518713.

It is buggy in dart2js.
chore: upgrade to barback 0.13.x

Pub in 1.4 is requiring barback 0.13 which has a breaking change in isPrimary (see https://codereview.chromium.org//223553008). This change allows Angular to target either barback 0.11.1+ or 0.13.0, depending on pub version.

End result is that this allows Angular to work on both stable and dev channel of Dart.

The corresponding DI change is https://github.com/angular/di.dart/pull/83

feat(Inheritance): Directives and components now support inheritance.

This patch supports the following scenario:

```
class Base {
  @NgAttr('foo')
  var foo;
}

@NgDirective(selector:'my-directive')
class MyDirective extends Base {
  @NgAttr('bar')
  var bar;
}
```

MyDirective will now have both properties, foo and bar.
