Make tags clickable
Tags look clickable in Leganto, even if they are not. It creates the expectation that something should happen. Some users might expect they will be taken to the full text of the citation, depending on the tag label.
What we would like to happen when a user clicks on a tag is that they get an overview of all the citations with the same tag. It's a quicker and more intuitive way than the current way of filtering by tag.
