Echo JS 0.11.0

First we used AirBnB but it was a bit inflexible and our company has enough man power to maintain its own config that reflects the consensus among our developers so we switched to eslint-config-schibsted.

Here are more companies/orgs that handle their own (shared with public) config:

 - https://github.com/walmartlabs/eslint-config-walmart
 - https://github.com/google/eslint-config-google
 - https://github.com/airbnb/javascript
 - https://github.com/gulpjs/eslint-config-gulp
