- initial CSS for container card outline, selection state, toolbar, etc
- adds `{{#koenig-card}}` component to be used inside of component card templates to handle the default card container HTML, mouse interactions, etc
- update `{{koenig-card-markdown}}` to use the new `{{koenig-card}}` component
- add render/edit mode views
- focus the textarea when entering edit mode
- updated `{{koenig-editor}}`
- add <kbd>Cmd+Enter</kbd> command to put a selected card into edit mode
- when inserting new cards put them into edit mode immediately
- move edit/select methods out of actions and into normal methods so that timing is easier to reason about
- skip `cursorDidChange` process when cursor changes as a result of a card selection, fixes issues with `selectCard` being triggered multiple times unexpectedly

- 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
