Title: Expression extractor transformer URI improvements

- Adding support for resolving 'packages/' uris (previously only handled '/packages/') from annotation templateUris.
- Adding support for /packages/ uris to the html_files transformer parameter for referencing package-relative URIs.
- Generating warnings for not-found files rather than build errors.

This is to address https://github.com/angular/angular.dart/issues/874
