@dzucconi: Styling articles list & more little boilerplates

Fills in some template & stylesheet action for the article list app. Adds template & integration tests.

Some project-wide things:
* Wires up javascript assets
* Adds a "view helper" lib that injects view helpers, like moment.js, to locals and globals client-side for ease of use in templates server/client
* Some minor layout styling cleanup + layout bootstrap client-side code
