* Add a navbar logo
* Reduce the fonts we load by specifying the one we want to use in the config file
* No more importing CSS thus faster loading
* Remove a few default properties from extra.css
* Bump copyright year
* Remove unneeded / add needed trailing slashes in config URLs
* Minor CSS tweaks
The links use a new `anchor` CSS class attached to an invisible `div`.
The class makes sure that the config option is not covered by the header
when you go to its link.
