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.
- App now shows how Angular handles untrusted URLs and resources
- E2e test covered new functionality
- Copyedits to prose
- Updated provider expressions to use latest syntax
