Acceptance ui

Things to do:
Make handlebars helper to make roles uppercase and replace _ in copyright_holders with a space.
Debug why I am not getting a response on successful POST


Unless it's imperative to initialize the default properties as empty strings, this model is probably not necessary.  The Collection will use `Backbone.Model` as the default model.

If you plan to add methods to this model though then go ahead and leave it, since this is just a WIP.
