Suggest Chicago Tribune in TODO

[brainwane]

As a followup to #12, here's a specific suggestion for a desired new source of obituaries (which could be added to a TODO section of README.md).

The Chicago Tribune obituaries section has an RSS feed. I've spot-checked and found at least one obituary of a local activist whose death the New York Times did not cover. Sometimes, as in this obit of Vincent Scully, the headline does not include the decedent's name, but the meta tags and other bits and pieces of the source code do, so the name check/edit function could plausibly suggest/grab from those. For example:

<meta name="Description" content="Legendary Yale historian Vincent Scully had a profound impact on the world of architecture, including in Chicago." />
<meta name="keywords" content="Vincent Scully, Harold Washington Center, Chicago, Architecture" />
trb.data.page.slug = 'ct-met-vincent-scully-obituary-20171201';
