WIP - Make the generator work with nested templates. If you generate a template for any of the child routes of a resource (i.e. people.index or people.new) you would do something like this:
 * ember generate -t people.index
The output file will be:
 * people__index.hbs
The registered template name in Ember.TEMPLATES will be:
 * people/index

This matches the way the Ember DefaultResolver#resolveTemplate looks up the template name.

The scaffolding update will be done shortly.
