Koenig is being fully rebooted, first port of call is to focus on getting the rich-text only aspect of mobiledoc-kit working with our popup toolbar.
- renames old koenig implementation (used for reference, will eventually be deleted)
- new `{{koenig-editor}}` mobiledoc-kit component implementation based on ember-mobiledoc-editor
- markdown text expansions
- new `{{gh-koenig-edtor}}` that wraps our title+editor and handles keyboard navigation between the two
- clicks below content will focus the editor
- new `{{koenig-toolbar}}` component for the popup formatting toolbar with improved behaviour and simplified code
requires https://github.com/TryGhost/Ghost/pull/9277
- added a `koenigEditor` feature flag
- modified the feature service to accept a `developer` boolean on the options object passed into the internal `feature` method, if `true` the feature flag won't be enabled unless the `enableDeveloperExperiments` config option is also enabled
- added "developer feature testing" section in labs that's only visible if `enableDeveloperExperiments` config flag is enabled
- added koenig editor toggle to the developer section in labs
- enabled a switch between the markdown and koenig editors
- modified the default value of the `mobiledoc` attr in the Post model to be a blank mobiledoc or blank markdown mobiledoc depending on the feature flag
- modified the `autofocus` switch in editor controller's `setPost` method so that it is always switched, even for new->edit where the post model isn't swapped
- added a compatibility check to the editor controller's `setPost` method that shows an alert and force enables the koenig editor if the koenig flag is not enabled and the opened post is not compatible with the markdown editor
- fixed various issues that have appeared due to the old koenig alpha becoming out of sync with master
no issue
- bump all deps with non-breaking changes
- bump yarn.lock sub-dependencies
- add `eslint` as a top-level dependency to satisfy peerDeps and fix linting when using Atom
no issue
- upgrade `ember-ajax` to 3.0.0
- `ember-ajax` [now passes the payload through directly](https://github.com/ember-cli/ember-ajax/releases/tag/v3.0.0) rather than trying to normalize it so all our error handling needed to be updated
closes https://github.com/TryGhost/Ghost/issues/6458
- swap `ember-sortable` for `ember-drag-drop` in navigation UI
- extract PSM tag input into new `{{gh-psm-tags-input}}`
- add new `{{gh-token-input}}` that wraps `ember-power-select` and `ember-drag-drop` to replicate the previous selectize based tags input
- enhance `{{gh-psm-tags-input}}` behaviour to highlight selected primary tag and show "primary/internal" in selected tag titles
- 🔥 remove `selectize`
- 🔥 remove `jquery-ui`
- 🔥 remove unused `{{gh-navigation}}` component
