html() shouldn't return own tag

From querypath created by neyaoz: technosophos/querypath#121

First of all, THANK YOU!

I am adding suffix to title by this way:

$qp->find('title')->html(
    $qp->find('title')->html() . ' (Suffix)'
);

Return is:

<title><title>Example Title</title> (Suffix)</title>

I can use innerHTML() for same job, but in jQuery don't return own tag and they says This method uses the browser's innerHTML property about html() method in API site. I think you should create outerHTML() method for results with own tag.

I need to check on this again, but I think the report is right. Should add this to the next QueryPath release.
