Contributors improvements

[haarg]

This improves the handling of contributors. It refactors the code some, allowing the contributor list to be shown on the module pages as well as the release page. It also includes authors listed in the metadata to the contributor list, and removes the releaser. This fixes #1270. Finally, it improves the formatting of the list so the 'and x contributors' label doesn't move when showing the list, and limits the width of the list so it lines up nicely with the rest of the sidebar.

I wonder if we should use Unicode::Collate to sort the contributor names?

The list already comes sorted (it's an array, not a hashref of keys), so it's not unreasonable to respect the order that it comes in. (For some dists I'm sorting the names by number of contributions, descending.)

When writing this, I wanted author names to show up first. And collaborators have a defined order in the meta file already.

Looking at it now though, it looks a little sloppy. Presenting the authors first is probably good, but maybe marking them somehow to distinguish them from the rest of the list. Possibly using a small icon near them with a tooltip.
