Legacy renderer (#1184)

* Include two versions of Marked.js

* Include two versions of Marked.js

* Working two different render pipelines

Adds stylesheet "styleLegacy.less"
Adds markdownHandler "markdownLegacy.js"
The BrewRenderer will switch between these and the new pipeline dependent on the "version" prop passed in.

* Mustache-style div blocks

* Legacy snippets & columnbreak

* Codemirror styling for Div Blocks

* Lint

* Codemirror highlights for inline Divs as well

These will turn red `{{class Content}}`

Multi-line divs will turn purple

```
{{class,class2
content
}}
```

No real need for these to be different colors. Just for testing.

* More lint

* Update dependencies.

* Adding Button to switch render pipelines

* Update Marked.js

* Popup alert to refresh page when renderer changed

* Don't compress files in Development (very slow)

* Block DIV or inline Span depending on {{ placement

* \column emits a Div instead of Span

* Allow share page to use new renderer

* {{ divs no longer need empty lines. Spans work in lists.

* Typo

* Typo
