Feature Request categories_as_class, posttype_as_class

[dleigh]

Hi,
I'm intrigued by the tags_as_class feature, but I'd probably be more interested in a categories_as_class and posttype_as_class feature such that I could use the category slug or the post-type slug as a class name to allow different styling depending up on which category it is. For now, perhaps I can make do with the tags but it's not ideal.

Thanks!
