WYSIWYG editor that outputs HTML instead of Markdown

**Is your feature request related to a problem? Please describe.**

it is common for jekyll (and other static generator) sites to use html as body format instead of markdown.


I would like to configure the body widget to use an HTML WYSIWYG editor, instead of a markdown WYSIWYG. Where the content outputs are HTML.

I have this on a couple sites, for many different reasons. I will have a collection that uses HTML instead of Markdown as the content. Mostly when a page needs **more customization** than working in markdown. very similar to the standard Wordpress editor.

**Describe the solution you'd like**

Would like a widget configuration type of `html` that embeds a WYSIWYG editor with html output. I would use this in place of the `markdown` widget

**Describe alternatives you've considered**

```html

CMS.registerWidget('richtext', RichTextControl, RichTextPreview)

```
