This fixes various issues such as:
- missing space in Dart version between the live demo and demo source
links.
- Live example link directing to Plunker for Dart.
The main mixins (`liveExampleLink`*) used to support the generation of
links now assume reasonable default values for their arguments, and in
most cases the defaults are used.
* Dart example links: use http vs https
As agree to with @kwalrath.
Be more DRY when referencing examples and excerpts. E.g.,
```jade
+makeExcerpt('quickstart/ts/app/app.component.ts', 'import',
'app/app.component.ts (import)')
```
can now be just
```jade
+makeExcerpt('app/app.component.ts', 'import')
```
Defined new mixin for examples named `makeProjExample` using this new
scheme.
The original `makeExample` has been left untouched.
Applied new mixins to quickstart.
