Title: Save original Backbone.sync implementation

Saves a copy of Backbone.sync to Backbone.originalSync before overriding, although this may not be the proper naming/namespacing. This is necessary when you need to sync with non-rails servers side-by-side with a rails server without having to have those other servers allow rails-specific headers in CORS.
