* Ember app Integration test validates Release Build and Web process loading Static Artifacts; includes fix to read custom error files via file server at runtime instead of at build time.

* Bump to current heroku/nodejs version

* All buildpack versions at 1.0.0

* Workaround pack registry collision during integration test
