Upadte styles for new Clay Card Grid List Markup

[carloslancha]

We changed a little the markup of the ClayCardGrid component in order to be like ClayList's one and to fix some issues with the soy compilation. We need to update Clay's demos and add (if needed) styles to make it looks fine again.

Here the new markup:

<ul class="card-page">
	<li>
		<h4 class="card-section-header">Folders</h4>
	</li>
	<li class="card-page-item-directory">
		<div class="card-type-directory......></div>
	</li>
	<li class="card-page-item-directory">
		<div class="card-type-directory......></div>
	</li>
	<li>
		<h4 class="card-section-header">Recipes</h4>
	</li>
	<li class="card-page-item-asset">
		<div class="card-type-asset......></div>
	</li>
	<li class="card-page-item-asset">
		<div class="card-type-asset......></div>
	</li>
</ul>

@pat270 If we need to add classes to any element in this markup just let us know. Thx!
