Notify New Relic only if app ID and key are set (#194)

* Notify New Relic only if app ID and key are set

This allows setting the app ID to false when deploying to environments not monitored by New Relic. You'll still receive an error message if you don't manually override newrelic_app_id.

* Update CHANGELOG for #139
