- add a mousemove event handler that shows the (+) next to blank paragraphs when the pointer is over them
- fix sticky button when adding a card mid-document by hiding it, we get another `didReceiveAttrs` call with the new range when adding a blank paragraph so it's still shown in that situation
- fix the incorrect button position when adding a card at the bottom of the doc by re-positioning in the next runloop. Problem seems to stem from the component card being rendered after we get the new range so our position calculations are out of sync

- use the `{{inline-svg}}` helper instead of having SVGs inlined manually in the component template
- rename the koenig icons directory
- add the koenig icons directory to the list of locations used by `{{inline-svg}}`

- re-implement the (+) card/list selection menu from the old Koenig alpha with improved positioning and event handling
- buttons work for the currently available cards - `<hr>` and `markdown`
refs https://github.com/TryGhost/Ghost/issues/9311
- add `{{koenig-card-markdown}}` component that renders an auto expanding textarea with the markdown card value
- add `{{card-markdown}}` that is an alias of `{{koenig-card-markdown}}` for backwards compatibility - all of our pre-1.0 alpha cards and our current markdown implementation do not have the `koenig-` prefix in their card names

- adds the `koenig-card-image` card that renders an `<img>` element
- adds text expansion to convert markdown images into the new image card

- use a similar approach as used in `ember-mobiledoc-editor` to render a div into the editor canvas then use Ember's `{{-in-element}}` helper as a wormhole to render an ember component card into the new div
- adds a `createComponentCard` util for setting up the necessary rendering boilerplate for Ember component cards

- pressing <kbd>Shift+Enter</kbd> will create a `soft-return` atom that adds a `<br>` element to the doc
- emulates many rich-text editors that have a similar functionality where it's desirable to add line breaks rather than starting new paragraphs

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
