When a heading is used in .card-header, the margin bottom makes the layout uneven.

Created by: cfarquharson

The card heading <div class="card-header">Featured</div> allows a user to fake out a header style, but if you try to put put an actual heading in that div, the display is odd as there is default 8px margin on the bottom. Can this be modified to match the effect that was previously available in panels?

I even tried that <div class="card-header"><h3 class="card-title">Special title treatment</h3></div> but that didn't fix it and instead created a 12px margin on the bottom.
