Title: Allow for an ignore "Defaults" block in the YAML

I'm managing multiple apps, and I want to be DRY, so I need a place to define some YAML nodes to then reference:

```yaml
defaults:
addons: &addons
pgbackups: plus
sendgrid: starter
papertrail: choklad
heroku-postgresql: dev
config: &config
BUNDLE_WITHOUT: "development:test"
AWS_ACCESS_KEY_ID: 'key'
AWS_SECRET_ACCESS_KEY: 'secret'

app1:
stack: cedar
app: awesome-app-the-first
addons:
<<: *addons
config:
<<: *config
DOMAIN: "awesome-app-the-first.herokuapp.com"
AWS_BUCKET: 'bucket'
```
