Move most views to Backbone. Resolves issue #79.

(Since this is a collection, pluralization would be great)

Also, passing in an argument to the constructor of a Collection does something you probably don't want -- it becomes a member of the collection (at least until the real results are fetched). The way to do this properly is:

    new OpenDisclosure.Contributors([], { candidate: id })

and then in the collection's `initialize` function,

    this.options.candidate
