noLink -> addLink

Replace the variable "noLink" by "addLink". This saves you the
two seconds for thinking about the multiple negation
`#unless noLink #else ..`. `#if addLink #else ..` is more
readily grasped.
Please do `<a class="inline-item publication" {{#if addLink}}href="{{path}}"{{/if}}>`. HTML is to be processed by the computer and not human, so it does not matter where is space, but it is much easier to read the template if there are no strange spaces you have to think about how they merge together.
