no issue
- the conditional for removal of trailing blank paragraphs was not sufficient to handle paragraphs where the first child element was not a text node such as when the content of the last paragraph is italic
- switched to a method that fully walks the DOM of the last paragraph node to extract its equivalent `.textContent` value for use in the "last para is blank?" check

- handle König Editor format for 2.0
- adapted importer to be able to import 1.0 and 2.0 exports
- added migration scripts
- remove labs flag for Koenig
- migrate all old editor posts to new editor format
- ensure we protect the code against mobiledoc or html field being null
- ensure we create a blank mobiledoc structure if mobiledoc field is null (model layer)
- ensure you can fully rollback 2.0 to 1.0
- keep mobiledoc/markdown version 1 logic to be able to rollback (deprecated code)

We've identified some changes we need to make to the HTML output of the [new Koenig editor](
https://forum.ghost.org/t/koenig-editor-beta-release/1284/102) for future proofing and consistency across cards.
- the `<div class="kg-post">` wrapper around post content has been removed
- for image cards the `.kg-image-wide` and `.kg-image-full` classes have been changed to `.kg-width-wide` and `.kg-width-full` and applied to the `<figure>` element rather than the `<img>` element
Before:
```html
<div class="kg-post">
<figure class="kg-image-card">
<img class="kg-image kg-image-wide" src="...">
<figcaption>example wide image</figcaption>
</figure>
</div>
```
After:
```html
<figure class="kg-image-card kg-width-wide">
<img class="kg-image" src="...">
<figcaption>example wide image</figcaption>
</figure>
```

- added `DomModifier` class to walk a SimpleDom document and modify as needed
- adds `id` attributes to `h1`, `h2`, etc heading tags
- converts H* tag content to a dasherized string for the id attribute (dasherized id's are different to the smushed ids that are generated by our markdown converted but there are no backwards-compatibility concerns here)
- if a duplicate id is detected then add a `-1`, `-2`, etc suffix to the id
- use `DomModifier` after converting mobiledoc to SimpleDom but before serialising to html
- switched top-level var declarations to es6
refs https://github.com/TryGhost/Ghost/issues/9505
- updates mobiledoc converter's `render` method to accept a `version` argument
- `1` === Ghost 1.0's markdown-only renderer output
- `2` === Koenig's full mobiledoc renderer output
- switch between mobiledoc renderer versions in Post model's `onSaving` hook
- version 1 by default
- version 2 if Koenig is enabled (currently behind dev experiments config + labs flag)
- version 2 if the post's mobiledoc is not compatible with the markdown-only renderer
- "version 2" full-Koenig mobiledoc renderer output
- wraps content in a `.kg-post` div
- removes wrapper around markdown and html card output
- adds classes to image card output including selected image size/style
- standardises es6 usage across mobiledoc related files
