MarketPress Suggestion - Add MP Body Class

I would like to suggest that MarketPress have a standard body class of "store", "shop" or even "mp" built in. The framework we use allows me to add a custom class to the body element of each of my pages. However, since MP pages are virtual, this isn't possible.

I've seen other users asking about this, so I believe it could benefit many people.

Thanks,
Darrin
