Title: Update preview styling to match styling at GitHub.com

This PR updates minor styling for the preview pane contents to match the styling of Markdown at GitHub.com (recently updated).

Minor fixes for:

- General typography
- Code blocks

What's missing is GitHub.com's syntax highlighting colours.
