Add stuar.tc to Planet Drupal

The feed passes validation.

I added the feed (https://www.drupal.org/aggregator/sources/2010), but when I click on update items, I get the following error.

The feed from Stuart Clark - Experimenting with Druxt seems to be broken, because of error "Attribute without value" on line 4.

It doesn't then aggregate articles from the feed.

The error is shown by aggregator_parse_feed() when xml_parse() fails to parse the feed.

I could not say what the error means, as I don't see any missing attributes.

I know there are reports about errors caused by feeds created on Github, on this queue.
