Create config that maps out DOM attributes to React props

The config will be used when converting DOM node attributes
to React props.

Map out the following:
- DOM attribute names
- standard properties
- RDFa properties
- non-standard properties

Used React's HTMLDOMPropertyConfig as source:
https://github.com/facebook/react/blob/master/src/renderers/dom/shared/HTMLDOMPropertyConfig.js
