- Use *ONLY* the official bundles when importing code. No imports from
`@angular/core/src/...` since those are incompatible ES6 modules now.
- Copy a bunch of private NG2 APIs that are not exported by the
bundles:
  - facade/lang + facade/collection
  - parse5_adapter
  - Renderer `CONTENT_ATTR` CSS constant
  - AnimationDriver interface definition
  - url_tree -> `containsTree` from `@angular/router`
  - `private_import_core`, `private_import_platform-browser`,
    `private_import_compiler`
- DetachedLoader no longer loading stuff inside a child ViewContainerRef
- DetachedLoader now properly using component factories.
- Lazy require animation driver module in renderer to work around a
  circular import issue in tns-core-modules.
- Router pushState now called before new component activation. Update
  location strategy hacks to accommodate that.
