Convert to Ember.js.

[cmeiklejohn]

First, let me apologize for the massive size of this pull request. I explored breaking this apart into a bunch of smaller commits, but it was going to be too difficult as the introduction of the Ember router forced a bunch of changes across the entire application.

Outline of the changes in this pull request:

• Add a set of rebar plugins to be used when compiling the application to concatenate JavaScript files and compile Handlebars templates.
• Upgrade jQuery; add Ember.js, Handlebars and Minispade.
• Deprecate pjax.
• Introduce the router for routing page requests.
• Convert the Ring and Snapshot pages over to Ember MVC.
• Use legacy action pub/sub code to keep cluster page functioning for the time being as it's being deprecated.
• Implement new webmachine modules for providing more RESTful resources which no longer return unnecessary data.
• Use ember-data to load cluster and partition information, convert snapshot page to derive state of cluster rather than use an additional 3rd endpoint for this information.
• Back button support, filters and pagination now have URL's /ring/filter/node/dev1@127.0.0.1/page/2, for instance.

Outstanding issues:

• Sidebar is not properly collapsing, @jgnewman maybe you could take a look at this?

As we do not have automated tests for any of the visual states, we need to pretty extensively test this before merging.

Ok, found one bug:

On the ring page, there is numbered pagination. Sometimes I have to click one of those numbers multiple times before it reacts to the click. The amount of times I have to click the number before it responds varies which leads me to believe it is somehow related to the ajax timer.

@jgnewman Disabling the polling doesn't fix the problem -- I'm investigating further.

@jgnewman Can I bug you for one more round of testing? I went through and reorganized the files better so we can keep better track of what we're going to be deprecating, and I also added a ton of jsdoc.
