Note we're delegating the `t` method because i18n-tasks doesn't detect
code like `ApplicationController.helpers.t` and so reports we aren't
using the `admin.stats.graph` translations.
Using <h3> headings for the links had two disadvantages.
First, it was the wrong heading level to use, since there was no <h2>
tag before it.
Second, headings are supposed to be followed by content associated to
that heading; here, we had no content following the headings.
So we're using a list of links and giving it a heading. We're adding
styles so the page still looks like it used to, although these styles
are certainly asking for improvements.
