Title: `default_attributes` and `override_attributes` are required in all roles

According to the [documentation](http://wiki.opscode.com/display/chef/Roles), both `default_attributes` and `override_attributes` are optional in a role definition. Without this patch, it's not possible to use a role that doesn't have both of those variables defined.
