feat(jsdoc package): use `jsdoc` rather than `js` doc-extractor

The `jsdoc` doc-extractor is compatible with the `js` version but provides
additional functionality.  The code following the jsdoc comment block
is provided to the doc as an extra property that can be used by successive
doc-processors.  For instance, to extract the name of the described code
item if no @name tag is provided.
feat(examples/index.template): allow ng-app to be defined in the example

By setting the ng-app-included attribute to true on an example we can
have the ng-app directive appear inside the example text rather than
being added externally to the generated index.html.

This is useful in examples that are actually show-casing the ng-app
functionality.
