Include Angular component templates as strings in the app bundle using
the stringify Browserify transform and use them from directives using
'template' instead of 'templateUrl'.

This is faster, because it avoids going through the async $http
machinery to load templates, but it is also synchronous, which generally
means fewer surprises due to async template loading and specifically in
the context of the <excerpt> directive will be useful as it will make it
possible for the <excerpt> directive to measure the height of its
content in the link function, because all components inside the
exercept's content will have been fully resolved at that point.
