Subject: [PATCH] Add anchor.js for pages using the `default` layout.

 * adds styles for anchor.js (similar to the official Bootstrap docs)
 * currently results some of the generated links to have a suffix (e. g. examples.html#templating-1) added due to sections having the same ID as the headline copy that we want to link to
