- add `deleteCard` action to `{{koenig-editor}}` component and pass it through to the component cards
- required modifying the `_deleteCard` behaviour so that it doesn't always try to move the cursor
- use `onLeaveEdit` action from `{{koenig-card}}` in the markdown and html cards to check if their payload is empty and remove the card when exiting edit mode
- fixed `onLeaveEdit` action firing when card first rendered

- fix overzealous matching of inline formatting
- ensure the match starts with a space or the start of the paragraph
- ensure the start matched chars are not followed by a space
- ensure the end matched chars are not preceded by a space
- avoid matching more MD chars than expected
- allow text expansions to work when editing text in the middle of a paragraph
- do not add a trailing space after reformatting in this case

- add a basic HTML card that renders a CodeMirror editor
- adjust styles so that CodeMirror styles for the markdown editor don't affect CodeMirror instances inside Koenig

- 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
