No longer works with srcset

I wrote a fix, so that the srcset functionality is available.

In wp-display-header.php add this line in the method init()
$this->hook( 'theme_mod_header_image_data' );
and add this method:

public function theme_mod_header_image_data($header_image_data)
{
	if (is_category() OR is_tag() OR is_tax())
		$active_header = $this->get_active_tax_header();
	else if (is_author())
		$active_header = $this->get_active_author_header();
	else if (is_singular())
		$active_header = $this->get_active_post_header();

	if (isset($active_header) AND $active_header)
	{
		$_uploaded_header_images = get_uploaded_header_images();
		foreach ($_uploaded_header_images as $id => $data)
		{
			if ($data['url'] == $active_header)
			{
				$header_image_data = $data;
				break;
			}
		}
	}

	return $header_image_data;
}

I had to modify the fix because the current/active header image URL wasn’t containing the hostname while the URLs in header image data array do, so also trying to match the URL inside the other:

if (($data['url'] == $active_header) or strpos($data['url'], $active_header) !== false)
