Add the current language to the body class

I'm not 100% sure this feedback applies because I'm not using Zen; however, I borrowed the zen_preprocess_page function for my own theme. I needed to also add the language body class, but I had to change $language->prefix to $language->language to get it to work. The $language->prefix variable was empty on my pages for some reason, but $language->language worked great.

New patch doing this "properly" (e.g. adding a new element to the $classes array prior to building the body_classes variable) attached. Marking R&TBC, because I've just used this on a production site and it's fine. And this issue is ages old - be good for multilingual site builders to get this in to the next release. ;-)

Actually there is the language selector you can use?

That's cool. Didn't know about that. It probably does negate the need for this patch, but it's little known, so in a way the class is easier because it's obvious to all.

I think we've gone a bit body class crazy in Drupal 7. This type of class is really easy to add if you need it. But I think the vast majority of sites are single language sites (sites in Europe being an exception).
