closes#1818
Previously, the markdown of some chapters was converted to Jade markup
to support the conditional exclusion of TS prose parts in Dart
chapters. This commit reverts some of that back to clean markdown,
thanks to a few custom directives.
Change `ngFor=“#…”` to `ngFor=“let…` in code. All are .dart files
except for `app_component.html` which also has changes for:
- `<inpuf var-foo…`> to `<input ref-foo…>`
- `#docregion` tag name updates from var-foo to ref-foo.
- Other misc updates to minimize diffs with TS version of file,
whitespace differences were ignored.
+ Minor update to sync up Dart prose with TS prose.
