Title: Specify a namespace for the REST adaptor which is added to all the ajax URLs

Usage:
App.store = DS.Store.create({ DS.RESTAdapter.create({ namespace: 'ember' }) });

Result: Calling App.store.find(App.Person, 1) would send a request to /ember/people/1 instead of /people/1

You can get the same result if you reopen all your models and add an url to them, but if you have lots then it isn't very DRY.
