Fetch wikipedia page for comma in name

<a href="/wiki/David_Howell,_Baron_Howell_of_Guildford" title="David Howell, Baron Howell of Guildford">David Howell</a>

We already had logic to catch this case, but were simply emitting the name.
Now we fetch the linked page, and parse it for /political/ references, that
normally suggest the party.
