Filter/Catelog columns dynamic

Set product columns to be dynamic so that there will be a three column
prod page when filter is present, and a four column page when not.
Filter results styles started

Use parent data does not appear to work w/ search results.
Featured products carousel products

Tags to show for the featured products carousel on homepage added so
that correct products are shown in that carousel.
Also added a "No Image Available" background to products to account for
imageless products.
Product list tags

Started sorting out product list tags, some need to be moved to
different location on the product, but it shouldn't be difficult once
all locations for all tags are determined.
