Twenty Thirteen: improve styling for RSS widget title

[aaroncampbell]

The RSS widget links it's title, so it doesn't look like it fits with the other widgets.

23571.diff styles linked widget titles to match the other widget titles. Links are still underlined on hover, so they're still discoverable as links.

@sabreuse Tiny thing with your patch -- can you put new selectors on a new line? We're following the WP CSS guidelines, see "Structure" here: ​http://make.wordpress.org/core/handbook/coding-standards/css/#structure.

Otherwise, the technique should work well and I can push the fix in.

23571.2.diff​ Updates the patch to follow WP CSS guidelines, also uses better CSS selectors for widget titles as suggested in #23580.

Do we really want to have them in the same color? It's a link after all, the others aren't.

I prefer it to be the same color. I think it looks best. However, I'm open to another option but I think the RSS Widget header should be further differentiated from the links in the widget content.

Any suggestions?

I think it's fine if it's the same color. On hover it changes to denote a link.
