no issue
- align Travis config more closely to default ember-cli setup
- run Chrome in headless mode in CI (Travis + `ember test`, `ember test --server` is "dev" mode)
- install yarn via install script rather than npm
- remove broccoli cache from Travis cache (not sure it ever worked?)
- remove forced node-sass install (no longer needed)
- add `testem` as a top-level dep to force the latest version (ember-data is pinned at 1.15)
no issue
- bump core `ember`, `ember-data` and `ember-cli` related dependencies
- remove deprecated `MODEL_FACTORY_INJECTIONS` flag
- update files to better match `ember-cli new` output for easier diffs during upgrades
no issue
- switch `jscs` and `jshint` inline config to `eslint` config
- fix eslint errors, predominantly in tests where the config now the main app config more closely
