Clickable section header links

[garymm]

It's really nice to be able to get a link to a specific section.
GitHub's built in Markdown renderer does this.
For example on this page: https://github.com/pages-themes/slate/blob/master/README.md

I can click on "Usage" and get this URL: https://github.com/pages-themes/slate/blob/master/README.md#usage.

Could you turn this on by default or add an option to enable it in the Slate theme?
