Comment 10 for bug 558419

Adding tabindices to the elements in the form is proving prohibitively difficult due to the way that Zope handles widgets and actions, so I'm going to go with Dustin's other suggestion and add a new formatter which will make the links open in a new page.

Incidentally, it turns out that I was wrong about updating the bug reporting guidelines themselves; those links are created by Launchpad (hence the new formatter).
