Live reviews for #80

This pull request should handle showing live reviews content delivered via the API at :homeId/reviews

It should also display the first review (if there is one) on the summary view.

Things that are undefined and therefore likely to change:
The state of the summary view if there are no reviews (current like this: http://up.jeremiak.com/X0ku)
The display of the reviews view if there are no reviews (currently like this: http://up.jeremiak.com/X0GX)

This PR has nothing to do creating reviews, that will be taken care of in #76
