[fix] Allow props to be passed down to child component

[QuicheSama]

react-markdown-github depends on react-markdown but does not pass most react-markdown props down to it's dependent component. This prevents users from overriding properties to get the behavior, or access the features they need. This simply passes the props through.

Once you've updated the CHANGELOG, 👍

Let's avoid adding new dependencies like rip-out if we can do this in pure JSX.

If you do the spread first in JSX this shouldn't be necessary, right? e.g.

render() {
  const renderers = {
    heading: this.renderHeading,
    ...this.props.renderers
  };	     

  return <ReactMarkdown { ...this.props }
    renderers={ renderers }
    transformLinkUri={ this.transformLinkUri }
    transformImageUri={ this.transformImageUri } />;
}

[dusave]

Actually, that would work now. Originally, I suggested that to be able to override the transformLinkUri and transformImageUri calls, but that’s no longer needed since they’re called as callbacks in those functions. Let’s do it that way, as long as we don’t change it in the future to not allow the user to provide their own override of a prop.

Agreed. @QuicheSama please update this to use the JSX spread technique outlined in my previous comment.
