Proper ember template paths

I believe this should fix the Ember template issue found in the second screenshot here (https://assembly.com/coderwall/wips/318).

In production, ember templates are stored at Ember.TEMPLATES.  Using console, and executing:
`Ember.TEMPLATES["ember/templates/events/view"] -> undefined`
`Ember.TEMPLATES["events/view"] -> function (n,i){return i=i||{},t.call(r,e,n,i.helpers,i.partials,i.data)}  `

This is a bit hairy at the moment to test properly on a local server.  Requires running rails in production mode, which is not a simple matter.  Having at least a staging application running a production environment would be helpful for work like this and to just have a general sanity/review process for deployment.
