Deprecated app.yaml items

[skipatrol]

When deploying using gcloud app deploy the first two lines that are written in the app.yaml file when running gae:setup have been deprecated and need to be removed: application: <app_id> version: 1

It's really straightforward to remove these manually, but it won't deploy with them in there so I thought you might want to know so that they can be removed from the artisan process. Thanks!
