Twenty Thirteen: Remove hgroup

[obenland]

With the removal of the <hrgroup> element from the spec, let's remove it in Twenty Thirteen too.

I'm pretty sure we'd blow back compat if we'd attempt to remove it in older themes.

hgroup? Can you please link to discussion and relevant docs for the removal?

Can we get rid of the extra div element? Seems like we could apply the same styles to the anchor element, since it's a block-level element and always present.

.1 removes the entire element (hgroup or div) and moves CSS and JS references to class value of "masthead" instead.

How do you plan on dealing with the hgroup cruft in html5.js?

Leaving it for now, will push an update once the author has a new version. It's very minor, in my opinion.

.2 updates to use home-link as class value instead of moving masthead.
