Copy Hash Links

[jpdevries]

Make it easy for people to copy links to sections of the documentation. Headers already have ids need to make them anchors to allow people to access them without viewing source.

To prevent screen readers from reading the headings as links

<h2 id="yolo"><span a11y-hidden>Yolo</span><a href="#yolo" aria-hidden>Yolo</a></h2>

I don't think daux lets us easily do this, but would be nice. Perhaps as a shown-on-hover/focus link/paragraph icon like github does it when it shows markdown in readmes?
