Update to Angular 0.9.10 and a few bug fixes

- pubspec.lock updated, in particular to Angular 0.9.10.
- Renamed a type in route (to match rename made in Angular).
- `ViewRecipeComponent.recipeMap` declared `@NgOneWay` (since it
doesn’t change the map).
- `ViewRecipeComponent.recipe` now handles null maps.
