Added basic CRUD view

I've been using django-angular for a while now, like it a lot, figured I could contribute something.

Since angular's $resource provides basic CRUD functions out-of-the box (see: http://docs.angularjs.org/api/ngResource.$resource ) I've coded a generic view to support this on server side.

While I see the three-way data binding does exactly that (and even more) sometimes one might not want to use sockets. Plus this is a clean and simple solution.

If you find it useful and merge-worthy I'll be happy to add some docs and unit tests.
