FEATURE: Attribute Display More/Less link

Added a setting to limit the number of attributes displayed per attribute group in the Browse by Attribute Snap-in. The number of attributes will show and a More/Less link is displayed underneath to show/hide the remaining attributes.

The following CSS style is needed to hide the extra attributes.

.MoreAttributes { display: none; }

and we recommened adding

.MoreAttributesLink { cursor: pointer; }
