closes#1807
- e2e tests now also cover the tax calculator.
- Dart app updated to match TS (it had no sales tax calculator).
- TS sample source cleanup (e.g. removed many unnecessary `docregions`).
- Prose updated to include @kwalrath's revisions from a while ago, Ward's comments, and
some of my edits as well.
Contributes to #1598 and #1508.
Also update dart_to_js_script_rewriter dependency to ^1.0.1,
and change most angular2.dart imports to be core.dart instead.
The pipes example broke without the angular2.dart import, so I let it be.
The server-communication sample has never worked for me,
so I changed it but might have broken it further.
