HTML5 Header/Footer sections

[jalberts]

I noticed that the featured posts' title is not being wrapped in a <header> block. The StudioPress themes using HTML5 output their featured posts (standard Genesis Featured Posts widget) with the following structure:

<header class="entry-header">
    <h2 class="entry-title">
        <a href="http://example.com/example-post/">Example Post</a>
    </h2>
    <p class="byline post-info entry-meta">
        <time class="entry-time" itemprop="datePublished" datetime="2014-07-23T14:37:26+00:00">July 23, 2014</time> By <span class="entry-author" itemprop="author" itemscope="itemscope" itemtype="http://schema.org/Person"><a href="http://example.com/author/personx/" class="entry-author-link" itemprop="url" rel="author"><span class="entry-author-name" itemprop="name">Person X</span></a></span>
    </p>
</header>

The default CSS styling for, say the by line, relies on this structure and these classes. Specifically, they target .content .entry-header .entry-meta. So the header with its class, and the entry-meta class on the post-info <p> (which is not included in the output from this plugin).

It's easy enough to add the class in, but I thought I'd take a look at wrapping the title/byline and adding in a wrap for the post-meta with footer, if genesis_html5() returned true as a PR.

The problem is, the plugin creates and prints both parts separately. I see at least two options, but I thought I'd see which you'd prefer for a PR (or if you have a different idea):

1. Merge the current do_byline() and do_post_title() functions into one function, generate the entire <header> section, and print it.
2. Output the <header> wrap between both functions:
   • If byline position set to after title, output opening <header> in do_post_title().
   • If byline position set to before title, output closing </header> in do_post_title().
   • If byline position is set to after title, output closing </header> in do_byline().
   • If byline position is set to before title, output opening <header> in do_byline().

The latter is a bit more confusing, but I wanted your preference on which way to go with that.

I think for <footer> I can put that into the post-meta output.

On a related note, the latest HTML5 themes are also now correctly using <h1> instead of <h2> for the article title. I can submit a PR to conditionally handle that, too, if you'd like.
