no issue
- ran [ember-native-class-codemod](https://github.com/ember-codemods/ember-native-class-codemod) to convert the majority of remaining EmberObject based controllers and components to native class syntax using the `@classic` decorator
- skipped older style modal components (`components/modal-*.js`) due to observed incompatibilities in some cases
no issue
- ran [es5-getter-ember-codemod](https://github.com/rondale-sc/es5-getter-ember-codemod)
- [es5 getters RFC](https://github.com/emberjs/rfcs/blob/master/text/0281-es5-getters.md)
- updates the majority of `object.get('property')` with `object.property` with exceptions:
- `.get('nested.property')` - it's not possible to determine if this is relying on "safe" path chaining for when `nested` doesn't exist
- `.get('config.x')` and `.get('settings.x')` - both our `config` and `settings` services are proxy objects which do not support es5 getters
- this PR is not exhaustive, there are still a number of places where `.get('service.foo')` and similar could be replaced but it gets us a long way there in a quick and automated fashion
no issue
- add eslint-plugin-ember, configure no-old-shims rule
- run `eslint --fix` on `app`, `lib`, `mirage`, and `tests` to move imports to the new module imports
- further cleanup of Ember globals usage
- remove event-dispatcher initializer now that `canDispatchToEventManager` is deprecated
no issue
* move "save on first change" behaviour into editor controller
* allow TAB events to be specified in keyEvents hash of gh-input
* replace mobiledoc-kit/gh-koenig with a SimpleMDE based editor
- remove `gh-koenig` in-repo-addon from `package.json` so that test files etc aren't loaded
- remove `mobiledoc-kit` dependencies
- extends `gh-editor` to handle file drag/drop
- adds `gh-uploader` and `gh-progress-bar` components to handle file uploads in a more composable manner
- adds `gh-simplemde` component that wraps SimpleMDE
