Correct vertical alignement

Hi Harry,

I used the `flag` object in a project and I've some "issue" with vertical alignement.

I forked your `flag` jsfiddle to illustrate my question : http://jsfiddle.net/pqYdA/

I think that by default the `flag` object can remove the bottom margin of the last element in the body (like in
the media object). What do you think ?

Thanks, Florian.
