For now, work around a Foundation bug.

https://github.com/zurb/foundation/issues/4619
Render job partials directly (closes #67).

If we render job partials in a controller or to a string, they get
rendered in an isolated view context.  That means that if they
set content_for (e.g., :javascript), that content gets eaten
rather than rendered, and that's keeping our page-by-page JS from
actually showing up.
