* update docs home banner
* update example and main repo pubspec.yaml files
* update shredder tests
(Not strictly necessary, but avoids tripping regex triggers when doing
updates.)
* plunker builder removes files and scripts not needed in plunkers (e.g., systemjs.config.js)
* no longer adds placeholder README.md (deemed a distraction)
* tag is now "Angular" instead of "Angular2"
* new plnkr.json "includeSystemConfig" option adds systemjs.config.js back; needed for testing plnkrs.
* incidentally changes comment "Polyfill(s)" to "Polyfills" in all index.html
* chore(test): add protractor4
* fix lint, remove boilerplate files, fix less gen
* separate scripts between package.json
* ignore a2docs.css in boilerplate
* remove tslint in _examples
* update to beta.22
* Dart SDK 1.19.0 or later is required
* minor edits to sample app titles to e2e tests pass
* Renamed “Angular 2” to “Angular” so that shared e2e tests pass.
* Tweak to QS prose.
* chore(ng2/dart): update from beta.1x to beta.18
Update made to all `pubspec.yaml` files and to relevant prose.
Note that pipes was back a beta.15; the rest were at beta.17.
* chore(pipes/dart): update ngFor microsyntax and transform method param
Updates to pipe example source code:
- Pipe `transform()` method parameters
- `ngFor` microsyntax, from `#` to `let`
Update gulpfile and project to add a tsconfig to protractor test folders
Change all sample e2e-spec.js -> e2e-spec.ts
Split typings between e2e-spec & app code
Use same config for all e2e tests
Only 1/3 e2e specs truly converted.
Most don't pass because they fail TS transpile by Protractor due to missing type annotations
